Abstract: A series of bis( diphenylphosphino )alkanes complexes of tantalum (III) chloride of the type Ta2CI6[Ph2-P(CH2)n - P-Ph2 ] (where n = I to 6) and Ta2CI6[Ph2-P-CH=CH-P-Ph2] have been synthesised by the reaction of tantalum pentachloride with bis(diphenylphosphino) alkanes v iz, 1,2-bis(diphenyl phosphino) methane (dppm), 1,2- bis( diphenylphosphino )ethane (dppe), 1,3-bis( diphenyl phosphino )propane (dppp), 1,4- bis( dipheriylphosphino )butane (dppb), I ,5-bis( dipheny I phosphino) pentane (dpppent), 1,6- bis( diphenyl phosphino )hexane (dpph), and cis-I,2-bis(diphenylphosphino)ethylene (dppen). The complexes have been characterised by elemental analysis, magnetic moment data, IR, IH, 31P and 13NMR spectral studies.
