MnSb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnSb2 cluster. Mn(1) is bonded in a bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. The Mn(1)-Sb(1) bond length is 2.00 Å. The Mn(1)-Sb(2) bond length is 1.98 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one Mn(1) atom. In the second Sb site, Sb(2) is bonded in a distorted single-bond geometry to one Mn(1) atom.
