Tin Tetra-ethyl, Sn(C₂H₅)₄

Tin Tetra-ethyl, Sn(C₂H₅)₄, prepared from zinc ethyl arid stannous chloride, according to the following reaction:

2SnCl₂ + 4Zn(C₂H₅)₂ = Sn(C₂H₅)₄ + Sn + 4Zn(C₂H₅)Cl,

is a combustible liquid having a density of 1-187 at 23° C.; it is insoluble in water and boils at 181° C. Tin tri-ethyl iodide, Sn(C₂H₅)₃I, exists, to which there correspond an oxide, hydroxide, and various salts; likewise the di-ethyl di-iodide, Sn(C₂H₅)₂I₂, and salts such as sulphate, nitrate, acetate. The ethyl stannic compounds resemble those of methyl described above.
