The first metal substituted stannatrane, Os(Sn- [OCH2CH2]3N)(η2-S2CNMe2)(CO)(PPh3)2, has been synthesised by reaction between triethanolamine and the triiodostannyl osmium complex Os(SnI3)(η2-S2CNMe2)(CO)(PPh3)2: the transannular SnâN distance of 2.422(4) à indicates a bonding interaction which is not seen in the corresponding silatranyl complex Os(Si[OCH2CH2]3N)- (η2-S2CNMe2)(CO)(PPh3)2 which has an SiâN distance of 3.176(6) à .

MHCl(CO)(PPh 3 ) 3 (MRu, Os) with (CH 2 CH)SnR 3 is a good general route to the coordinatively unsaturated osmium and ruthenium stannyl complexes M(SnR 3 )Cl(CO)(PPh 3 ) 2 ( 1 : MRu, RMe; 2 : MRu, R = n-butyl; 3 : MRu, R = p -tolyl; 4 : MOs, RMe). These coordinatively unsaturated complexes readily add CO and CN- p -tolyl to form the coordinatively saturated compounds M(SnR 3 )Cl(CO)L(PPh 3 ) 2
