121Sb Mössbauer studies on dialkylantimony(V) compounds of the types R2Sb(OMe)3, R2Sb(OAc)3 and R2Sb(O)OH

Abstract

Mössbauer spectra of three series of dialkylantimony(V) compounds have been measured to study bonding and structural properties of these compounds. Trialkoxodialkyl and triacetatodialkylantimony(V) compounds have octahedral structure. The former are dimeric, containing bridging methoxo groups, the latter are monomeric, containing a bidentate acetato ligand, for which the bite angle is distorted from 90°. Dialkylstibinic acids, R2Sb(O)OH, have tetrahedral coordination around the antimony atom. The additive model for the Electric Field Gradient is used to interpret much of the quadrupole coupling data
