A novel triazidoruthenium(iii) building block for the construction of polynuclear compounds†
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
