High pressure High temperature Synthesis, Magnetic Properties and X ray Absorption Spectroscopy of Phases RE3Sn7 and hp RESn3 x (RE = Tb, Ho, Er)m). hp HoSn3 x transforms exothermally at 460 K and ambient pressure into the low pressure modification HoSn3 x indicating that the ordered Cu3Au type arrangement is a metastable high pressure phase., A second set of phases is identified as compounds RE3Sn7 (RE = Ho, Er) being isotypic to the ambient pressure modifications Gd3Sn7 and Tb3Sn7 (space group Cmmm; lattice parameters a = 434.95(7) pm, b = 2615.6(6) pm, c = 442.09(7) pm for Ho3Sn7 and a = 434.29(5) pm, b = 2607.2(4) pm, c = 441.49(5) pm) for Er3Sn7). The crystal structure of compounds RE3Sn7 is interpreted as an intergrowth of AlB2 , CaF2 and AuCu3 like segments. Analysis of the chemical bonding in Er3Sn7 by means of the electron localizability approach reveals two center Sn Sn bonding in the AlB2 like segment and multi center bonding in the AuCu3 and CaF2 like motifs., The electrical resistivity of 31 cm at 300 K reveals that hp HoSn3 x is a metallic conductor. The phases hp RESn3 x and RE3Sn7 (RE = Ho, Er) show paramagnetic Curie Weiss behavior of the rare earth metal ions Ho3+ and Er3+, respectively. Ho3Sn7 and Er3Sn7 order antiferromagnetically at 10.0 K and 8.2 K, respectively. The high pressure phases RESn3 x show no magnetic order above 2 K. XAS measurements on the compounds Tb3Sn7 and hp TbSn3 x indicate a 4f 8 configuration evidencing the oxidation state +3 for terbium.

Isolated and Edge Connected Tetramers {(C2)2O2Dy14} in the Crystal Structures of {(C2)2O2Dy14}I24 and {(C2)2O2Dy12}I18 with a = 972.97(14) pm, b = 1033.03(13) pm, c = 1677.0(2) pm, = 101.42(1) , = 92.72(1) , = 112.75(1) and V = 1509.3(3) 106 pm3, Z = 2, and is isotypic with the analogous yttrium and erbium cluster complexes. The tetrameric {(C2)2O2R14}I32 cluster complexes consist of corner sharing tetrahedra with endohedral oxygen atoms to which octahedra encapsulating C2 dumbbells are attached on both sides. The tetramers are connected via iodide bridges yielding, e.g., {(C2)2O2Dy14}I24. Connection of the tetramers through common cluster edges leads to the one dimensional polymeric cluster complex {(C2)2O2Dy12}I18. It crystallizes in the space group P6/m with a = 2024.18(8) pm, c = 1299.21(4) pm, V = 4610.1(3) 106 pm3 and Z = 8. Dedicated to Professor Bernd Harbrecht on the Occasion of His 60th Birthday| 2010

MOFs by Transformation of 1D Coordination Polymers II: The Homoleptic Divalent Rare Earth 3D Benzotriazolate $\rm ^3_\infty[Eu(Btz)_2]$ Initiating from $\rm ^1_\infty[Eu(Btz)_2(BtzH)_2]$ marks the final thermal reaction step within the system europium/1H 1,2,3 benzotriazole. It can be obtained by a reaction of the metal with a melt of benzotriazole above 230 C or from thermal treatment of the 1D coordination polymer$\rm ^1_\infty[Eu(Btz)_2(BtzH)_2]$ (Btz = 1,2,3 benzotriazolate anion, C6H4N3 ; BtzH = 1H 1,2,3 benzotriazole, C6H5N3), which is formed first at about 100 C from the same reagents. In addition to the trivalent rare earth ions it can thus be shown that also divalent EuII together with benzotriazole exhibits transformation of a 1D coordination polymer into a 3D MOF. The homoleptic framework $\rm ^3_\infty[Eu(Btz)_2]$ exhibits a high thermal stability (525 C) for an exothermically decomposing coordination compound. As $\rm ^3_\infty[Eu(Btz)_2]$ is always obtained as a microcrystalline product, structure solution and refinement were achieved by X ray powder techniques. For further characterization 151Eu M ssbauer, IR, and Raman spectroscopy as well as micro and thermal analysis were carried out.

Cadmiumreiche Cadmide des Systems Na/K/Cd. Cadmium rich Cadmides of the System Na/K/Cd, a = 958.75(9) pm, Z = 3, R1 = 0.042) was confirmed and refined using single crystal data. The border phases of the new series KNaxCd11 x (x = 0.87/0.53; tetragonal, space group I41/amd, a = 1222.98(6)/1215.17(12) pm, c = 766.05(4)/769.05(7) pm, Z = 4, R1 = 0.021/0.024) form the BaCd11 structure type, which was previously unknown for alkaline metal compounds. The barium site of the basic structure type is occupied by potassium, whereas one cadmium site with slightly higher coordination number and interatomic distances is statistically occupied by sodium and cadmium atoms, which leads to the phase width given above. In the structure, the atoms of the two pure Cd positions form channels running along the tetragonal c axis, in which the K and Na/Cd atoms alternate. A similar structural motif is found in the second border compound K3Cd16, which has been described formerly as K0.37Cd2 with a complete disorder of potassium atoms inside the channels. The detailed inspection of single crystal image plate diffractometer data revealed satellite reflections indicating an almost commensurately modulated superstructure. In the new structural model with a quadrupled c axis (tetragonal, space group P4/nnc, a = 915.2(6), c = 1159.0(4) pm, Z = 2) three potassium cations per channel are partially ordered. Both the significant structural factors (strongly changing radius of the countercations) and the electronic criteria, which can be assessed from the pseudo band gap calculated using FP LAPW DFT methods, are discussed.

Polymorphism of Eu8In3 and the Solid Solution (CaxEu1–x)8In3Gäbler, Frank / Niewa, Rainer et al. | 2010

Polymorphism of Eu8In3 and the Solid Solution (CaxEu1 x)8In3c (No. 167), a = 957.7(1) pm, c = 5674(1) pm, Z = 12, R(F) = 0.020, wR(F2) = 0.038), the high temperature phase triclinic (P$\bar1$ (No. 2), a = 992.67(6) pm, b = 998.08(4) pm, c = 1007.89(5) pm, = 99.140(4) , = 101.172(5) , = 119.452(6) , Z = 2, R(F) = 0.035, wR(F2) = 0.080) in the Ca8In3 structure type. The densities ( triclinic = 6.36 g cm 1; trigonal = 6.90 g cm 1) as well as the synthesis conditions are compatible with the assignment as high and low temperature phase. The two polymorphs can be rationalized as polytypes of close packings of In with occupation of all octahedral holes and 5/6 of the tetrahedral voids. In this description, indium atoms realize the motif of a double hexagonal stacking for the low temperature modification and a cubic stacking for the high temperature phase. Alternatively, both structures can be described by the occurring coordination polyhedra (tetrahedra for europium, cubes, icosahedra and cubicosahedra surrounding indium). Eu8In3 is versatile to europium substitution by calcium, with little preference for either europium or calcium on the sites exhibiting the highest degree of distortion from tetrahedral shape (Ca4Eu4In3: P$\bar1$, a = 975.2(2) pm, b = 987.1(2) pm, c = 992.8(2) pm, = 99.12(3) , = 101.06(3) , = 119.59(3) , Z = 2, R(F) = 0.023, wR(F2) = 0.044).

Ternary Transition Metal Acetylides AI2M0C2 (AI = K, Rb; M0 = Pd, Pt): Neutron Diffraction Studies and Electronic Propertiesm1, Z = 1) were refined from time of flight powder neutron diffraction data (Polaris, ISIS/RAL) at room temperature and 4.5 K. The resulting C C distances within the C22 anion are in the range 124.4 124.7 pm (295 K). This is distinctly longer than the expected distance for a C C triple bond (120 pm). At low temperatures slightly longer C C distances are found (125.0 126.7 pm), which is due to an increasing wobbling of the C2 dumbbells around their center of gravity with increasing temperature. This is also reflected in the temperature dependence of the lattice parameters a and c. Lattice parameter c, which is parallel to the C2 dumbbells, decreases with increasing temperature, whereas a shows a typical positive thermal expansion. Differing to previous work ternary palladium acetylides A2PdC2 were obtained as red (A = Na) and yellow powders (A = K, Rb) by using a slightly improved synthesis. By means of diffuse reflectivity direct bandgaps were determined to 2.09 eV (A = Na), 2.55 eV (A = K), and 2.77 eV (A = Rb). This is in good agreement with direct bandgaps obtained from band structure calculations. These band structure calculations indicate very small indirect bandgaps of only a few tenth of an eV.
