Methyl stannic chloride, SnCH3Cl3






Methyl stannic chloride, SnCH3Cl3, prisms melting at 53° C.; methyl stannic bromide, SnCH3Br3, needles melting at 53° C.; methyl stannic iodide, SnCH3I3, yellow prisms melting at 86.5° C., are formed by the action of the corresponding halogen hydracid on methyl stannic acid, SnCH3-O-OH, and are converted into the latter substance by the action of ammonia. Methyl stannic acid, which may be regarded as methyl stannonic acid, CH3-SnO-OH, is obtained by the action of methyl iodide on potassium stannite, thus:

HSnO-OK + CH3I + KOH = CH3SnO-OK + KI + H2O,

the resulting potassium salt being then decomposed by carbonic acid. When warmed with alkali solution, however, the potassium salt gradually produces dimethyl stannone and potassium stannate, thus:

2CH3SnOOK = (CH3)2SnO + SnO(OK)2,

by a change analogous to that which acetate undergoes when heated:

2CH3COOK = (CH3)2CO + CO(OK)2;

and when dimethyl stannone is distilled with alkali it yields trimethyl stannic hydroxide, (CH3)3-Sn-OH, thus:

3(CH3)2SnO + 2KOH = 2(CH3)3SnOH + SnO(OK)2.
