Abstract

Reaction of [Ru ^VI(N)(sap)Cl] with excess NaN ₃ affords a novel paramagnetic triazidoruthenium(iii) complex [Ru ^III(sap) (N ₃) ₃] ^2-, which is isolated as a PPh ₄ ⁺ salt (1). Reaction of 1 with Ni ²⁺ and Co ²⁺ ions produce two isostructural hexanuclear [Ru ₄M ₂] compounds, [Ru ^IV ₄M ^II ₂(μ ₃-OMe) ₂(μ-OMe) ₂(μ-N) ₂(μ-N ₃) ₂(μ-O _phenoxy) 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 Ni ²⁺ in 2 and Co ²⁺ in 3via the methoxy bridges. © 2012 The Royal Society of Chemistry.
