TENFOLD INTERPENETRATION OF GIANT HEXAGONAL R-12(12)(126) NETS IN THEHYDROGEN-BONDED STRUCTURE OF 1,1,1-TRIS(4-HYDROXYPHENYL)ETHANE-4,4'-BIPYRIDYL (2 3)/
In the 2:3 adduct of 1,1,1-tris(4-hydroxyphenyl)ethane [or ethane-1,1,
1-triyltris(4-phenol)] and 4,4'-bipyridyl, 2C(20)H(18)O(3).3C(10)H(8)N
(2), the components are linked by O-H ... N hydrogen bonds [N ... O 2.
780(2), 2.745 (2) and 2.731(2)Angstrom] into puckered two-dimensional
nets built from giant hexagons, each involving six units of each compo
nent. There are ten such independent nets, all multiply interwoven, wi
thin the structure.
