Antimony(III)triazadiphosphorine complexes, [N(PPh2NR')2SbOGO] (where R' = -Ph or -SiMe3 and G = -CHMeCH2-, -CHMeCH2CMe2-, -CH2CH2CH2-, -CH2CMe2CH2-, -CH2CEt2CH2- or -CMe2CMe2-), have been synthesized by the reaction of bis-phenylated acyclic phosphazene ligand, H[N(PPh2NPh)2], or bis-silylated acyclic phosphazene ligand, H[N(PPh2NSiMe3)2], with various cycloalkylenedioxyalkoxystibine, [OGOSb(OR)], (where R = -Et or -Pri) under anhydrous and inert conditions. The mixed phosphazene-glycolate derivatives of antimony(III) have been characterized by elemental analysis (C, H,Nand Sb), molecular weight determination, mass, IR andNMR (1H, 13C and 31P) spectroscopies. The studies suggested a bidentate mode of bonding by phosphazene ligand that may lead to _-trigonal bipyramidal coordination around the antimony. Ahydrolytically stable and rubber like material has been obtained on pyrolysis of [N(PPh2NPh)2SbOCH2CMe2CH2O] which, probably, has an oligomeric composition like {N(PPh2)2(NPh)2Sb}n .
