The differential pulse polarographic behaviour in dimethyl sulphoxide (DMSO) of 14 organotin(IV) compounds having the general formula R 3 SnX (R = Me, Ph; X − = NCS − , N 3 − , N 3 − , NO 3 − , OH − , NCO − and OAc − ) and n Bu 3 SnCl and n Bu 2 SnCl 2 has been studied. The peak potential was found to depend markedly on the organic group and to a lesser extent on the nature of the anion X. The phenyltin compounds were reduced at lower potentials than the corresponding methyltin compounds. The data obtained could be used for trace determination of these compounds. Linear calibration curves were obtained over the concentration range of 2.8 × 10 −4 to 1.9 × 10 −6 mol dm −3 .
