Cocrystallization of 1,2-bis(4-pyridyl)ethane (4,4’-bipyeth) with
resorcinol (res), 4-chlororesorcinol (4-Cl-res), and
4,6-dichlororesorcinol (4,6di-Cl-res) yields molecular solids
(4,4’-bipyeth). (res) la, 2(4,4’-bipyeth).2(4-Cl-res) 1b, and
2(4,4’-bipyeth).2(4,6-di-Cl-res) is with components held together by 0-H
. . .N hydrogen bonds. In 1a the components form an infinite 1D polar
array, whereas in 1b and is the components form OD four-component
complexes. Formation of the discrete assemblies is attributed to
peripheral steric effects, which block the solid-state polymerization.
