A tetranuclear cubane-like cluster [Ni4(HL)4(DMSO) 2]·2DMSO·H2O (1) and a dinuclear compound [Cu2Cl2(H2L)2]·1.5MeOH (2) (H3L=3-(2-hydroxy-benzylideneamino)propane-1,2-diol) have been prepared and characterized by X-ray single crystal diffraction, IR, and elemental analysis. The X-ray diffraction analysis indicated that the four metals of 1 showed a Ni4O4 cubane arrangement, and two of the six faces of the Ni4O4 cubane were capped by DMSO. Complex 1 is the first reported DMSO capped Ni4O4 cubane cluster. Complex 2 contains a u2-Cl bridged dinuclear core with each CuII ion exhibiting pseudo square pyramidal geometry.
