catena-Poly[[bis(dimethyl sulfoxide-κO)cerium(III)]tris(μ2-3,5-dinitrobenzoato-κ2O:O′)]

Abstract

The polymeric title compound, [Ce(C7H3N2O6)3(C2H6OS)2]n, exists as a linear chain along [111] as the three dinitrobenzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated CeIII atoms. The metal atoms are surrounded by eight O atoms in a square-antiprismatic environment. There are two independent formula units in the asymmetric unit. The S atoms of two of the four DMSO molecules are disordered in a 0.926 (3):0.074 (3) ratio.
