Three-dimensional homochiral transition-metal camphorate architectures directed by a flexible auxiliary ligand

Abstract

Reported here are four homochiral and one racemic chiral compounds assembled from transition metals (Fe2+, Co2+, and Ni2+), rigid enantiopure camphoric acid, and flexible 4,4'-trimethylenedipyridine; they feature an unusual homochiral three-dimensional supramolecular assembly (resulting from catenation of 4-connected bilayers) as well as a homochiral 3-fold interpenetrating diamond net and a noninterpenetrating primitive cubic net.
