Two new tetranuclear copper(II) complexes: Structure and magnetic studies

The syntheses, structural characterization and magnetic behaviour of two new tetranuclear copper(II) compounds with formulae [Cu4(μ2-PhCOO)2(μ-bdmap)2(μ1,3-N3)2(N3)2(H2O)2] 1, and [Cu4(μ2-PhCOO)2(μ-bdmap)2(μ1,3-N3)2(PhCOO)2(CH3OH)2] 2, in which bdmap is 1,3-bis(dimethylamino)-2-propanolato are reported herein. The magnetic behaviour of the two complexes has been checked giving a bulk antiferromagnetic coupling in the two cases with J values of −85.4 and −89.5 cm−1 for 1 and 2, respectively.
