Abstract

Mononuclear cis,cis,trans-[Ru(CO)2Cl2(Pz*H)2] (1) and dinuclear [Ru2(DMSO)3Cl2(Pz*H)× (μ-H)(μ-Pz*)(μ-DMSO)] (2) complexes (DMSO = dimethylsulfoxide and Pz* = 3,5-dimethylpyrazolate) are obtained by the reaction of KTp* in methanol (KTp* = potassium tris(3,5-dimethylpyrazolyl)borate) with [Ru(CO)3Cl2]2 and cis-[RuCl2(DMSO)4] precursors, respectively. These complexes are obtained from the degradation of the scorpionate KTp* ligand and characterized by IR, 1H NMR, and X-ray crystallography.
