Tin(IV) selenophosphate has been synthesized by mixing 0.05 mol dm<SUP>−3</SUP> aqueous solutions of tin(IV) chloride, sodium selenite and sodium dihydrogenphosphate in 1:1:2 ratio at pH=0. The chemical and thermal stabilities are investigated. A tentative formula has been proposed for tin(IV) selenophosphate on the basis of chemical composition, pH titration, IR spectrum and thermogravimetric anslysis. The distribution coefficients of metal ions have been determined in DMF, DMSO, DMF–HNO<SUB>3</SUB>, and DMSO–HNO<SUB>3</SUB> media. A number of binary, ternary, and quaternary separations of metal ions have been achieved on the columns of tin(IV) selenophosphate.
