Investigation of BINOL-3,3′-dicarboxylate as a ligand for the formation of extended coordination-based structures

Abstract

We provide a structural study of the ability of BINOL-3,3′-dicarboxylate, an inexpensive and readily accessible 1,1′-binaphthol-based ligand, to form extended self-assembled coordination polymers and frameworks in combination with divalent zinc and copper ions. While the structural diversity of herein described materials illustrates the untapped potential of the BINOL-3,3′-dicarboxylate in forming coordination polymer structures, we also provide the first example of an open two-dimensional framework established using this ligand as the only anionic, metal-bridging constituent.
