Abstract: In the crystal structure of the title compound, [Zn2(C8H4O4)2(C2H6OS)2]·5C2H6OS, four independent carboxylate units of the 1,4-benzenedicarboxylate groups chelate to two Zn atoms to give rise to -O-C-O-Zn...Zn- rings, the four O atoms around each zinc atom forming a square, above which is a dimethyl sulfoxide (DMSO) molecule and below which is the other Zn atom. The bridging mode of the 1,4-benzenedicarboxylate groups, one of which lies on a general position and the other two on inversion centers, leads to a layer structure having DMSO molecules between the layers. The uncoordinated solvent molecules account for about 80% of the volume of the unit cell.
