Sn with the content of 0.004% in the lithosphere is almost in presence of cassiterite and little in presence of Sn-contained sulfide. Since 1980s, the anticancer active study on organic complex compounds has attracted considerable attentions, it becomes another hot issue after the study on Pt. When time up to the year 1989, the anticancer active measurement of more than 2000 kinds of Sn-contained complex compounds have been carried out by Cancer Academy, U.S, with the results showing half of these Sn-contained complex compounds posses antileucocythemia(P388) activity. Thereafter, Sn-contained complex compounds synthesized by hydrothermal reaction also become a hot issue people focus on.
