Crystal structure of tetra-kis-(μ-2-hy-droxy-3,5-di-isoprop-yl-benzoato)bis-[(dimethyl sulfoxide)copper(II)].

Metal complexes of 3,5-diiso-propyl-salicylate are reported to have anti-inflammatory and anti-convulsant activities. The title binuclear copper complex, [Cu2 (C13 H17 O3 )4 (C2 H6 OS)2 ] or [Cu(II)2 (3,5-DIPS)4 (DMSO)2 ], contains two five-coordinate copper atoms that are bridged by four 3,5-diiso-propyl-salicylate ligands and capped by two axial dimethyl sulfoxide (DMSO) moieties. Each copper atom is attached to four oxygen atoms in an almost square-planar fashion, with the addition of a DMSO ligand in an apical position leading to a square-pyramidal arrangement. The hy-droxy group of the diiso-propyl-salicylate ligands participates in intra-molecular O-H⋯O hydrogen-bonding inter-actions.
