Bis(μ-2′-carboxylatobiphenyl-2-carboxylic acid-κ2O2:O2′)bis[(2,2′-bipyridine-κ2N,N′)(2′-carboxylatobiphenyl-2-carboxylic acid-κO2′)zinc(II)]

Abstract

In the dimeric title compound, [Zn2(C14H9O4)4(C10H8N2)2], the ZnII ions are pentacoordinated by one 2,2′-bipyridyl ligand and by three O atoms from three 2′-carboxylatobiphenyl-2-carboxylic acid ligands. Two of the 2′-carboxylatobiphenyl-2-carboxylic acid ligands act as bridging ligands and, together with two zinc(II) cations, produce an 18-membered ring system. The remaining 2′-carboxylatobiphenyl-2-carboxylic acid ligands work as monodentate ligands. The crystal packing diagram is consolidated by O—H...O hydrogen bonds.
