Abstract

Reaction of [RuVI(N)(sap)Cl] with excess NaN3 affords a novel paramagnetic triazidoruthenium(III) complex [RuIII(sap)(N3)3]2−, which is isolated as a PPh4+ salt (1). Reaction of 1 with Ni2+ and Co2+ ions produce two isostructural hexanuclear [Ru4M2] compounds, [RuIV4MII2(μ3-OMe)2(μ-OMe)2(μ-N)2(μ-N3)2(μ-Ophenoxy)2(sap)4 (MeOH)4] (M = Ni 2 or Co 3). The molecular structures of 1–3 have been determined by X-ray crystallography. 1 is a mononuclear ruthenium(III) compound where three azide ligands are bonded to ruthenium in a meridional fashion, while compounds 2 and 3 are isostructural hexanuclear compounds containing a defective face-sharing dicubane-like core with two missing vertexes. Variable-temperature dc magnetic susceptibility studies have been carried out for 2 and 3. These data indicate that there are four diamagnetic Ru(IV) ions in 2 and 3 and there is ferromagnetic interaction between the two Ni2+ in 2 and Co2+ in 3via the methoxy bridges.
