μ2-Oxalato-bridged tricopper(II) complex derived from 1,4,8,12-tetraazacyclopentadecane: Synthesis, structure and magnetic characterization

The complex [Cu(tacp)(H2O)]2[Cu(μ2-C2O4)2(ClO4)2] (tacp = 1,4,8,12-tetraazacyclopentadecane) was synthesized and structurally characterized. It exhibits weak antiferromagnetic coupling and two types of coordination modes were found for the bridging oxalate.
