[3] In tetramethyltin, the metal surrounded by four methyl groups in a tetrahedral structure is a heavy analogue of neopentane.

These methyltin chlorides are prepared via the so-called Kocheshkov redistribution reaction.

Di- and trimercaptotin compounds are used to inhibit the dehydrochlorination, which is the pathway for photolytic and thermal degradation of PVC.

[3] Tetramethyltin decomposes in the gas phase at about 277 °C; (CH3)4Sn vapor reacts with silica to give a (CH3)3Sn-grafted solid.

[4] In organic synthesis, tetramethyltin undergoes palladium-catalyzed coupling reactions with acid chlorides to give methyl ketones:[5]
