摘要：

[Cu(bmen)2(H2O)2]F2 center dot 4H2O (1) (bmen=N,N-dimethylethane-1,2-diamine) and [Cu(bmen)2(BF4)2] (2) exhibit ionic and molecular crystal structures, respectively. In both 1 and 2, Cu(II) exhibits tetragonally elongated six coordination in the 4+2 form with two chelate bmen in the equatorial plane; axial positions are occupied by weakly bound water in 1 while in 2 in these positions are fluorine from disordered BF4 . Packing in 1 and 2 are governed by hydrogen bonds (HBs). Magnetic studies from 1.8 to 300K reveal that 1 and 2 follow the Curie-Weiss law with parameters theta=-0.88K and g=2.04 for 1 and theta=-0.58K and g=2.13 for 2, suggesting the presence of weak antiferromagnetic interactions.
