A novel porous material constructed from linear helical cadmium(II) coordination polymer based on in-situ ligand reaction

A novel helical cadmium(II) coordination polymer cis,cis,trans-{[Cd(HIDC)(H2O)2]·1/3H2O}n (1) has been obtained by the solvothermal reaction of hydrated CdCl2 with 2H-imidazole-4,5-dicarbonitrile (HIMDN) in the presence of NH3·H2O. The packing of the six neighboring polymeric helical chains of the complex leads to a 1-D channel, which is occupied by lattice water molecules. The solid-state luminescence properties of 1 have been investigated at room temperature.
