trans-Carbonyl[dihydrobis(1,2,4-triazol-1-yl-κN2)borato]hydridobis(triphenylphosphine-κP)ruthenium(II) acetonitrile solvate

In the crystal structure of the title compound, [Ru(C4H6BN6)H(C18H15P)2(CO)]·C2H3N, discrete mononuclear complexes are found in which the Ru atom is coordinated by two triphenylphosphine (PPh3) ligands, one dihydrobis(1,2,4-triazol-1-yl)borate ligand, one carbonyl ligand and one hydride atom within slightly distorted octahedra. The two P atoms of the PPh3 ligands are trans positioned and the two N atoms of the chelating dihydrobis(1,2,4-triazol-1-yl)borate ligand occupy cis positions.
