A luminescent cadmium itaconate coordination polymer with rare 658 layer topology from in situ hydrothermal decarboxylation of trans-aconitic acid

The luminescent coordination polymer {[Cd(ita)(bpfp)(H2O)]•4H2O}n (1, ita = itaconate, bpfp = bis(4-pyridylformyl)piperazine) was synthesized via in situ hydrothermal decarboxylation of trans-aconitic acid. [Cd(ita)(H2O)]n undulating chains with gauche conformation ita ligands are connected into a very rare 4-connected 658 layered topology by long-spanning bpfp tethering ligands.
