Synthesis and Characterization of the Complex Triorganoantimony(V) Cations, R3SbL2+and R3Sb(L-L)2+

Abstract
Pentacoordinate cationic complexes of the types [R3SbL′2]Y2(I) and [R3Sb(L-L))Y2(II), (where R = CH3, C6H5 and P-CH3C6H4 L′ = DMSO, TPAO and TPPO; L-L = bipy and en; Y = BF4 or BPh4) have been synthesized and characterized by elemental analysis. IR and 1H n. m. r. spectral data and conductance measurements. IR data in dichloromethane suggest the absence of dissociation of complex cations. Spectroscopic data conform to the requirement of trigonal bipyramidal configuration for the complex cations.
