Di-μ-chlorido-bis[aqua(2,2′-bipyridine-κ2N,N′)chloridocobalt(II)]

Abstract

The title complex, [Co2Cl4(C10H8N2)2(H2O)2], is composed of two CoII atoms, each hexacoordinated by three Cl atoms, one 2,2′-bipyridine (bpy) ligand and one water molecule in a distorted octahedral geometry. Neighboring CoII atoms are linked together by two Cl bridges, forming a dinuclear CoII complex with inversion symmetry. There are intermolecular O—H...Cl hydrogen bonds and intermolecular π–π stacking interactions between adjacent bpy ligands [centroid–centroid distance = 3.617 (2) Å] in the structure.
