Abstract

A series of hitherto unreported solid salts of penta‐coordinated cations of the general formula [R2SbL3]3+, where R = C6H5, p‐ClC6H4, p‐CH3C6H4, p‐(CH3O)C6H4; L = DMSO, Ph3AsO, Py‐N‐oxide, DMF, α‐, β‐, and γ‐picoline have been prepared in the presence of tetraphenyl‐ and tetrafluoro‐borate counterions. The complexes have been formulated and characterized on the basis of elemental analyses, molar conductances, molecular weights, and solid state IR and solution state 1H NMR spectral data. The physico‐chemical data are consistent with five‐coordinate antimony complexes.
