Abstract
Imidazolate-bridged trinuclear(copper(II)–manganese(II)–copper(II)) complexes [CuLMn(tfa)2LCu]2H2O 1 and [CuLMn(hfa)2LCu]3H2O 2 have been prepared and characterized, where tfa=trifluoroacetylacetonate, hfa=hexafluoroacetylacetonate, H2L=unsymmetrical quadridentate Schiff base derived from the condensation reaction of acetylacetone, ethylenediamine, and 4-formylimi dazole with the mole ratio of 1:1:1. The magnetic susceptibility data were represented by a spin-only interaction model(1/2–5/2–1/2) with JMn-Cu value of −13 cm−1 for 1 and −8 cm−1 for 2.Keywords
