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.
