Solid-state self-assembly of 1,4-bis(2-carboxybenzyloxy)benzene in the presence and absence of aromatic amines

Abstract

Solid-state self-assembly of 1,4-bis(2-carboxybenzyloxy)benzene and its stoichiometric complexes with diamines such as 4,4′-bipyrydyl and 1,2-bis(4-pyridyl)ethylene are described with complete structural details. Carboxylic acid dimer formation and O-H⋯N-type hydrogen bonds were the major hydrogen bonding motifs in the crystal lattice. A wave-type topology was observed for the hydrogen bonded chains. © 2002 The Royal Society of Chemistry.
