The title compound, C13H22N4Si2+.2Br-.C2H3N, crystallizes from the solution of N-methylimidazole and 1,1-dibromosilacyclohexane in which it was prepared. Two Br- ions of the starting material are removed from the first area of coordination of the Si atom. The resulting species is a dication. The structure displays a six-membered silaheterocycle containing a tetracoordinated Si atom. The crystal was a racemic twin.
