摘要
A new convenient and efficient route for the synthesis of two very important hydroxo-bridged stepped-cubane copper complexes viz: [Cu4(bpy)4Cl2(OH)4]Cl2.6H2O (1) and [Cu4(phen)4Cl2(OH)4]Cl2.6H2O (2) have been obtained. This synthetic route from the mononuclear CubpyCl2 complex is easier, more reproducible and afforded the complex in a much higher yield than the other two previously reported procedures which were equally serendipitously discovered. The purity and formation of the complexes were confirmed with elemental (C,H,N) analysis and the details of the UV-Vis, Fourier transform infrared, electrospray ionization mass spectra of both complexes and the single crystal X-ray crystallography of 1 are presented and discussed. X-ray crystallography confirms the absolute structure of the complexes. The complexes were formed via the connection of four copper atoms to four hydroxide bridging ligands and four bipyridyl ligands with two chloride ligands. There are two coordinate environments around two pairs of copper atoms (CuN2ClO2 and CuN2O3) and each copper atom is pentacoordinate with square pyramidal geometry.
