Organotin-chelate compounds of the type R2SnOxCl, where Ox- is 8-quinolinolate, are formed from the interaction of R2SnCl2 and R2SnOx2. Chlorodiaryland chlorodialkyl-tin complexes undergo chloride substitution when treated with such reagents as lithium butyl, beta-diketones, iodide ion, ethoxide ion, and 8quinolinol. Evidence is presented to show that some of these products have disproportionated. Evidence is also presented that some compounds, notably C6H52 SnOxCl, CH32SnOxCl and CH32SnOxI, are examples of five-co-ordinate tin, while other compounds investigated, including a mixed chelate compound CH32SnOxC6H5COCHCOC6H5, appear to be examples of six-co-ordinate tin.
