摘要：

A trinuclear cobalt(III) complex, [Co-3(L-his)(3)(mu-OH)(3)(mu(3)-O)]ClO4.H2O (L-Hhis: L-histidine), containing an incomplete cubane Co3O4 core was isolated and the structure was compared with [Co-3(edma)(3)(mu-OH)(3)(mu(3)-O)](+) (Hedma: NH2CH2CH2NHCH2COOH) isomers. Using the edma and L-his as N-N-O type ligands, [Mo-3(L)(3)(mu-S)(3)(mu(3)-S)](+) complexes with a Mo3S4 incomplete cubane core were also prepared, and their structures were determined by the X-ray diffraction method. A structural similarity between [Mo-3(L)(3)(mu-S)(3)(mu(3)-S)](+) and [Co-3(L)(3)(mu-OH)(3)(mu(3)-O)](+) is discussed; it is suggested that three N-H...O inter-ligand (intra-molecular) attractive interaction has an important role in stabilizing the incomplete cubane structure.
