Abstract

A new inorganic–organic hybrid compound [Cd(H2L)(H2O)], 1, {where, H2L2− = 4,4′-sulfonylbis(phenylene)bis(oxamate)} has been prepared under solvothermal conditions. The compound has a three-dimensional structure. The compound exhibits strong luminescence behavior, and was used for the detection of chromate and dichromate anions in aqueous media at low concentrations. The compound exhibited high selectivity and recyclability for the detection of low concentrations (ppm levels) of chromate and dichromate ions. Compound 1 was also found to be an effective catalyst for the Knoevenagel condensation involving aromatic aldehyde and malononitrile under green solvent-free conditions with high yield and recyclability.
