Abstract A systematic study of pentavalent organoantimony compounds, (RC6H4)3SbX2 (R=H,p-CH3,p-F,p-Cl,p-CF3,o-CH3; X=Cl, Br), was carried out to examine the effect on Mössbauer parameters of the substituent on the aromatic ring. The Mössbauer parameters obtained in polycrystalline form reflected the steric effect caused by the position of the substituent on the aromatic ring. On the other hand, measurements in frozen organic solutions revealed that the electron density and electric field gradient at and around the antimony nucleus became smaller when the more electron-attractive group was introduced into thepara position.
