Abstract

A 3d-4d binuclear Cu(II)-Ru(III) complex exhibiting ferromagnetic spin-coupling [Cu(A)Ru(salen)(PPh3)]ClO4·MeOH has been synthesized and characterized, where H2A = N-(2-imidazolidene)-N′-(acetylacetonylidene)ethylendiamine and H2salen = N,N′-bis(salicylidene)ethylenediamine. The magnetic susceptibility data (4.2–300 K) were well reproduced by the equation derived from H = −2JSCu·SRu (SCu = 1/2, SRu = 1/2) with g = 2.04 and J = +6.55 cm−1. The ESR study indicated that the magnetic orbitals of Cu(II) and Ru(III) are orthogonal to each other.
