Crystal structure of catena-poly[calcium-di-μ3-benzoato-κ(6) O,O':O-μ2-(dimethyl sulfoxide)-κ(2) O:O].

In the title complex, [Ca(C7H5O2)2(C2H6OS)] n , the Ca(2+) ion (site symmetry m..) is surrounded by eight O atoms, six from two bridging-chelating tridentate benzoate carboxyl groups and two from a bridging dimethyl sulfoxide mol-ecule (point group symmetry m.
