Abstract The molecular structure of [Cu(sulfadimet)2 ].SO(CH ) (sulfadimet=sulfadimethoxine=4-p-aminobenzenesulfonamido-2,6-dimethox- 2 32 ypyrimidine) was determined by single crystal X-ray diffractometry. It crystallizes in the monoclinic space group P2/c with Z=4. The Cu(II) cation is in a distorted CuN square pyramidal coordination, involving four sulfadimethoxine molecules, one of them acting as a 5 bidentate ligand. The infrared spectrum is briefly discussed on the basis of the structural peculiarities of the complex.
