RESEARCH PAPERS - Crystal engineering using bisphenols: Interwoven ladders, sheet and framework structures in the binary adducts of 4,4'-sulfonyldiphenol with pyridyl)ethane, pyrazine (2-1), 4,4'-bipyridyl (W), trans-1,2-bis(4-pyridyl)ethene (1-1), 1,2-bis(4-pyridyl)ethane (1-1) and 4,4-trimethylenedipyridine (1-1), and in 4,4'-sulfonyldiphenol-4,4'-trimethylenedipiperidinewater (2-2-1) - The 2:1 adduct of 4,4'-sulfonyldiphenol and pyrazine takes the form of continuously interwoven molecular ladders; the 1:1 Adducts of 4,4'-sulfonyldiphenol with 4,4'-bipyridyl, 1,2-bis(4-1,2-bis(4-pyridyl)ethane and 4,4'-trimethylenedipyridine all consist of chains, further cross-linked by C - H...O hydrogen bonds. The hydrated adduct with 4,4'-trimethylenedipiperidine is a salt in which the components form a hydrogen-bonded three-dimensional framework

RESEARCH PAPERS - Crystal engineering using bisphenols and trisphenols. Complexes with 1,10-phenanthroline: Hydrogen-bonded chains in adducts with 4,4'-biphenol (1-1) and 4,4'-sulfonyldiphenol (2-3), p-p stacked chains in the (1-2) adduct with 4,4-thiodiphenol, and pairwise-interwoven nets in 1,1,1-tris(4-hydroxyphenyl)ethane-1,10-phenanthroline-methanol (1-1-1) - In its 1:1 Adduct with 4,4'-biphenol, 1,10-phenanthroline acts as a builder of hydrogen-bonded chains; in its 1:2 adduct with 4,4-thiodiphenol the diamine acts as a terminator of such chains, and in its 2:3 adduct with 4,4'-sulfonyldiphenol, both roles are manifest. In the methanol-solvated 1:1:1 adduct with 1,1,1-tris(4-hydroxyphenyl)ethane the 1,10-phenanthroline units act as chain terminators and the structure contams pairwise-interwoven nets
