The colourless title complex, [Zn2(C10H11O5)4(C2H6OS)2], crystallizes with one half-molecule in the asymmetric unit, the other half of the molecule being generated by a crystallographic inversion center. The structure shows a 2-O:O'-bridging mode of the four 3,4,5-trimethoxybenzoate ligands finally stabilizing the two ZnII atoms in the dinuclear complex in a distorted square-pyramidal environment. The fifth coordination site in the apical position of the pyramid is occupied by a coordinating dimethyl sulfoxide solvent molecule equally disordered over two positions.
