| Abstract: | Synthesis, Characterization, and Structure of Carbonyl and Hydrido Isocyanato Complexes of Ruthenium 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, β = 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. |
