(Ammine)(carbon-yl)[hydridotris(pyrazol-1-yl-κN(2))borato](triphenyl-phosphine-κP)ruthenium(II) chloride dichloro-methane disolvate.

In the title compound, [Ru(CO)(NH3)(C9H10BN6)(C18H15P)]Cl·2CH2Cl2, the coordination environment around the RuII atom is distorted octa­hedral. 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 inter­actions between the pyrazole rings [centroid–centroid distance = 3.764 (3) A] are also present.
