MnBiBiSi is alpha carbon monoxide-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one lambda2-bismuthanylidenesilicon molecule and one MnBi cluster. In the MnBi cluster, Mn(1) is bonded in a single-bond geometry to one Bi(1) atom. The Mn(1)-Bi(1) bond length is 0.72 Å. Bi(1) is bonded in a single-bond geometry to one Mn(1) atom.
