Mn Mn Sb Sb
MnSb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnSb cluster. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Sb(2) atom. The Mn(1)-Sb(2) bond length is 1.43 Å. In the second Mn site, Mn(2) is bonded in a bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. The Mn(2)-Sb(1) bond length is 1.43 Å. The Mn(2)-Sb(2) bond length is 1.10 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a single-bond geometry to one Mn(2) atom. In the second Sb site, Sb(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(2) atom.
