title: (Ammine)(carbon-yl)[hydridotris(pyrazol-1-yl-κN(2))borato](triphenyl-phosphine-κP)ruthenium(II) chloride dichloro-methane disolvate.
abstract: In the title compound, [Ru(CO)(NH(3))(C(9)H(10)BN(6))(C(18)H(15)P)]Cl·2CH(2)Cl(2), the coordination environment around the Ru(II) atom is distorted octa-hedral. One of the Ru-N(Tp) [Tp = hydridotris(pyrazol-1-yl)borate] bond lengths is slightly longer than the other two as a result of the influence of the trans CO ligand. In the crystal, N-H⋯Cl hydrogen bonds link the complex cations and Cl(-) anions. π-π inter-actions between the pyrazole rings [centroid-centroid distance = 3.764 (3) Å] are also present.
