Abstract: The electrophilic addition of [OsCI(NO)L2]2+ [L = deprotonated quinolin-8-ol (L1) Z = 0 and 2-(m-tolylazo )pyridine (L2), Z = 2] to alkylidenearylhydrazone, RCH=NNHPh (R = Me, Phor C6H4Me-p), in MeCN containing MeONa affords new complex of the type [OsAL2]n+ (A = anion of arylazo oxime, RC(=NOH)N=NPh; n=0 forL1 and n= I forL2]. An alternative synthesis of [OsAL2]n+ has been carried out by the reaction of [OsChL2]2 with RC(=NOH)N=NPh. paramagnetic [OsAL1 2] and diamagnetic [OsAL22]+ complexes have been characterised by physicochemical, megnetic and spectroscopic methods.
