title: Hydrogen-bond networks in tris(4-hydroxyphenyl)methane and its 1:1 molecular complex with 4,4'-bipyridine.
abstract: In tris(4-hydroxyphenyl)methane (or 4,4',4"-methanetriyltriphenol), C(19)H(16)O(3), molecules are connected by O-H.O hydrogen bonds [O.O = 2.662 (2) and 2.648 (2) A] into two-dimensional square networks that are twofold interpenetrated. In tris(4-hydroxyphenyl)methane-4,4'-bipyridine (1/1), C(19)H(16)O(3).C(10)H(8)N(2), trisphenol molecules form rectangular networks via O-H.O [O.O = 2.694 (3) A] and C-H.O [C.O = 3.384 (3) A] hydrogen bonds. Bipyridine molecules hydrogen bonded to phenol moieties [O.N = 2.622 (3) and 2.764 (3) A] fill the voids to complete the structure.
