摘要：

The title complex has been prepared and characterized by X-ray crystallography, magnetochemistry, cyclic voltammetry and H-1 NMR spectroscopy. The complex contains a [Mn-4(mu(3)-O)(2)](8+) core with bridging EtCO2- and chelating bpya groups. The magnetochemical studies indicate an S = 0 ground state as a result of antiferromagnetic exchange interactions between the Wit ions. The H-1 NMR spectra support retention of the solid-state structure on dissolution in MeCN. (C) 2002 Elsevier Science Ltd. All rights reserved.
