MnSiBi is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnSiBi clusters. Mn(1) is bonded in a single-bond geometry to one Si(1) atom. The Mn(1)-Si(1) bond length is 0.84 Å. Si(1) is bonded in a linear geometry to one Mn(1) and one Bi(1) atom. The Si(1)-Bi(1) bond length is 0.10 Å. Bi(1) is bonded in a single-bond geometry to one Si(1) atom.
