Bis(dimethyl sulfoxide-κO)tetrakis(μ₂-3,4,5-trimethoxybenzoato-κ²O:O′)dizinc

Abstract

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 μ2-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.
