2 adduct of tin tetrachloride with methylamine is reported. When pure monomethylamine gas reacts with tin (IV) tetrachloride in the molar ratio (CH3NH2 : SnC14) 4:1 and 6:1 in carbon tetrachloride, only one substance is obtained which is independent of the reaction time. The product is the simple 1:2 adduct of tin (IV) chloride and methylamine. The paper describes the synthesis and properties of this adduct including its i.r. spectrum.
