Abstract

The crystal structure of a 1D chain complex, [Cu(SCN)(deae)](n) (1) (Hdeae = N,N-diethylamino ethanol), with mixed bridges was determined. The structure is composed of a dimeric Cu(II) unit with two bridging μ³-η²-aminoethanolato ligands, while the units are bridged by end-to-end thiocyanato groups to form a 1D chain. The variable temperature magnetic susceptibility of 1 and [Cu(SCN)(dmae)](n) (2) (Hdmae = N,N-dimethylamino ethanol) in the temperature 5-300 K have been interpreted in terms of simple dimer model approximation (H = -2JS(A)·S(B)). The magnetic behaviors show that the aminoethanolato bridges mediate a moderately strong antiferromagnetic exchange interaction with the fitting values g = 1.96(3), J= -175(3) cm^-1 for 1 and g = 2.016(7), J= -205.4(7) cm^-1 for 2, respectively.
