Abstract

Hydride complexes [OsH2L4][L = P(OEt)3 or PPh(OEt)2] were prepared. Their reactions with arenediazonium cations led to the synthesis of [Os(RN[double bond, length half m-dash]NH)2L4][BPh4]2 and [OsH(RN[double bond, length half m-dash]NH)L4]BPh4(R = Ph, 4-MeC6H4, or 4-MeOC6H4) complexes which were characterized by 1H and 31P n.m.r. data (with 15N isotopic substitution). The compounds [Os(4-MeC6H4N[double bond, length half m-dash]NH)(4-MeC6H4NC)L4][BPh4]2 were also prepared. The reaction of the bis(aryldiazene) derivatives with NEt3 led to new five-co-ordinate aryldiazenido complexes [Os(RN2)L4]BPh4(R = Ph or 4-MeC6H4). Protonation of the diazenido compounds with CF3CO2H and HBF4 gave the six-co-ordinate mono(diazene)[Os(CF3CO2)(RN[double bond, length half m-dash]NH)L4]BPh4 and the five-co-ordinate [Os(RN[double bond, length half m-dash]NH)L4]BPh4(R = 4-MeC6H4) derivatives, respectively. Infrared and 1H and 31P n.m.r. data for these complexes are reported.
