Abstract

The synthesis, structures, and magnetic properties of four cyano-bridged M^IIRu^III₂ compounds prepared from the paramagnetic Ru^III building blocks, trans-[Ru(salen)(CN) ₂]^- 1 [H₂salen = N,N′- ethylenebis(salicylideneimine)] and trans-[Ru(acac)₂(CN) ₂]^- (Hacac = acetylacetone), are described. Compound 2, {Mn(CH₃OH)₄[Ru(salen)(CN)₂]₂} · 6CH₃OH·2H₂O, is a trinuclear complex that exhibits antiferromagnetic coupling between Mn^II and Ru^III centers. Compound 3, {Mn(H₂O)₂[Ru(salen)(CN) ₂]₂·H₂O}_n, has a 2-D sheetlike structure that exhibits antiferromagnetic coupling between Mn and Ru, leading to ferrimagnetic-like behavior. Compound 4, {Ni(cyclam)[Ru(acac) ₂(CN)₂]₂}· 2CH₃OH· 2H₂O (cyclam = 1,4,8,11-tetraazacyclotetradecane), is a trinuclear complex that exhibits ferromagnetic coupling. Compound 5, {Co[Ru(acac) ₂(CN)₂]₂}_n, has a 3-D diamond-like interpenetrating network that exhibits ferromagnetic ordering below 4.6 K. The density functional theory (DFT) method was used to calculate the molecular magnetic orbitals and the magnetic exchange interaction between Ru^III and M^II (Mn^II, Ni^II) ions. © 2005 American Chemical Society.
