Mn Mn Bi Sb
Mn Mn Bi Sb 0 3 - o o 1 2 - o o 
MnBiMnSb is beta oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one stibanylidynemanganese molecule and one MnBi cluster. In the MnBi cluster, Mn(2) is bonded in a single-bond geometry to one Bi(1) atom. The Mn(2)-Bi(1) bond length is 0.89 Å. Bi(1) is bonded in a single-bond geometry to one Mn(2) atom.
