Azido(benzonitrile-κN)[hydridotris(pyrazol-1-yl-κN2)borato](triphenylphosphine-κP)ruthenium(II)

Abstract

Facile ligand substitution is observed when the ruthenium–azide complex, [RuN3(Tp)(PPh3)2] [Tp,HB(pz)3, pz = pyrazolyl, PPh3 = triphenylphosphine] is treated with benzonitrile, yielding the title compound, [Ru(C9H10BN6)(N3)(C7H5N)(C18H15P)]. The asymmetric unit contains two crystallographically independent molecules. In each one, the RuII atom is six-coordinated in a distorted octahedral geometry by five N atoms from an htpb ligand, an azide ligand and a benzonitrile ligand and one P atom from a triphenylphosphine (tpp) ligand. The azide group is almost linear and is coordinated to Ru with an average Ru—N—N angle of 124.9 (3)°.
