Generation of Three-Dimensional Networks through Aliphatic Chain Disorder in a Divalent Metal Dicarboxylate/Organodiimine Coordination Polymer System

Hydrothermal synthesis has afforded coordination polymers incorporating the kinked dipodal organodiimine 4,4′-dipyridylamine (dpa) and the flexible aliphatic dicarboxylate suberate dianion, with a general formulation of [M(sub)(dpa)(H2O)]n (sub = suberate, M = Co, 1; M = Ni, 2). Both 1 and 2 exhibit crystallographically disordered suberate ligands, producing a three-dimensional “ligand vacancy” α-Po coordination polymer network composed of two different types of [M(sub)(dpa)(H2O)]n idealized layers.
