Ferrimagnetic copper-carboxyphosphinate compounds for catalytic degradation of methylene blue

Two novel copper coordination polymers constructed from a V-shape carboxylphosphinate ligand, which show a one-dimensional ladder-like chain structure and a three-dimensional framework, respectively. Magnetic analyses reveal weak ferromagnetic and antiferromagnetic couplings between the metal ions generating ferrimagnetic behavior in compound 1. Both two compounds show catalytic activities for degradation of methylene blue aqueous solution.180
