The reaction of phenyl hydrazine with tin(IV) fluoride results in the formation of the adduct SnF 4 · 2 C 6 H 5 NHNH 2 , but the reaction with tin(IV) chloride yields as many as four compounds of the emperical composition SnCl 4 · nC 6 H 5 NHNH 2 (n = 1, 2, 3 and 4). At low concentrations of phenyl hydrazine (upto the molar ratio SnCl 4 : C 6 H 5 NHNH 2 = 1:1), an 1:1 addition compound, SnCl 4 · C 6 H 5 NHNH 2 , is formed, but when the molar ratio SnCl 4 : C 6 H 5 NHNH 2 is increased, a base‐catalysed elimination of hydrogen chloride takes place resulting in the formation of amino basic tin(IV) chloride and phenylhydrazine hydrochloride. Tin(IV) chloride forms also 1:1 complexes with phenyl hydrazones and phenyl hydrazine hydrochloride. Interconversion, hydrolysis and thermal decomposition of some of these compounds have been investigated and their infrared spectra measured.
