(Benzonitrile-κN)chlorido[hydridotris(pyrazol-1-yl-κN2)borato](triphenylphosphine-κP)ruthenium(II) ethanol solvate

The reaction of [Ru(C9H10BN6)Cl(C18H15P)2] with benzo­nitrile leads to crystals of the title compound, [Ru(C9H10BN6)Cl(C18H15P)(C7H5N)]·C2H5OH. In the crystal structure, the environment about the ruthenium metal center corresponds to a slightly distorted octa­hedron with an average N—Ru—N bite angle of the Tp ligand of 86.6 (2)°.
