Synthesis, Characterization and Structure of Carbonyl and Hydrido Isocyanato Complexes of Ruthenium

Abstract. [Ru(CO)H(NCO)(PPh2Me)3] is formed during the reaction between [RuCl3(PPh2Me)3] and NaOCN in EtOH. The compound crystallizes in the monoclinic space group P21/n (a=1256.4(4), b=1487.2(2), c=1993.5(5) pm, b=97.28(1)°, Z=4). The distorted octahedral coordination sphere of RuII contains the phosphine ligands in meridional arrangement, their P atoms forming a plane together with the hydride ligand.
The reaction of [RuCl3(PPh3)2] with NaOCN in EtOH yields [Ru(NCO)-(CO)(CH3COO)-(PPh3)2] with trans coordinated Ph3P ligands.
The formation of hydrido, carbonyl and acetato ligands are due to the reaction of the transition metal with the solvent ethanol.
