Abstract
Imidazolate-bridged copper(II)–chromium(III)–copper(II) complex, [Cu(A)Cr(salen)Cu(A)]ClO4·3H2O, has been synthesized and characterized, where H2A = 4-(6-methyl-8-oxo-2,5-diazanona-1,5,7-trienyl)imidazole and H2salen = N,N′-di(salicylidene)ethylenediamine, respectively. The magnetic moment per molecule increases from 4.61 BM at 297.8 K to the maximum value 5.27 BM at 14 K, and then decreases to 4.42 BM at 4.4 K. The magnetic behavior shows that there operates a ferromagnetic interaction between chromium(III) and copper(II) ions through imidazolate group.Keywords
