The speciation of Sn(IV)-Br- in concentrated Br- media was determined, and the corresponding stability constants of Sn(IV)-Br- complexation were estimated. Electrochemical redox mechanism of Sn(IV)/Sn(II) in Br- media was newly proposed based on our Sn(IV)-Br- speciation results. The speciation of Sn(II)-Cl- in concentrated Cl- media was also determined, and we found the evidence of Sn(II)Cl5-, Sn(II)Cl62-, and Sn(II)Cl73-.
