Synthesis and Crystal Structure of a Triply-Bridged Binuclear Cobalt(II) Dichloroacetate

Abstract

A triply-bridged cobalt(II) tetracarboxylate complex, [Co 2 (µ-OH 2 )(µ-CHCl 2 COO) 2 (η 1 -CHCl 2 COO) 2 (py) 4 ] has been prepared and its crystal structure has been determined by single crystal x-ray diffraction to find that in this dinuclear cobalt(II) complex, the two metal centres are bridged by a water molecule and two dichloroacetato ligands. Each Co(II) centre is further coordinated to one monodentate dichloroacetato and two pyridine ligands. Supramolecular interactions stabilize the complex in the solid state.
