Methylbismuth dichloride is the organobismuth compound with the formula CH3BiCl2. It is a pale yellow solid. The compound can be prepared in two steps from , first by methylation with methylmagnesium chloride. Treatment of the resulting methyldiphenylbismuthine with hydrogen chloride cleaves the two phenyl-bismuth bonds.

The compound adopts a polymeric structure wherein each square pyramidal Bi center is bound to four chloride ligands and an apical methyl group. The bismuth centers are interconnected by doubly bridged chloride centers.[1]
