KMnBi is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KMnBi cluster. K(1) is bonded in a distorted L-shaped geometry to one Mn(1) and one Bi(1) atom. The K(1)-Mn(1) bond length is 2.05 Å. The K(1)-Bi(1) bond length is 1.99 Å. Mn(1) is bonded in a 1-coordinate geometry to one K(1) atom. Bi(1) is bonded in a distorted single-bond geometry to one K(1) atom.
