VMnSn2 crystallizes in the monoclinic Cm space group. V(1) is bonded in a single-bond geometry to one Mn(1) and one Sn(2) atom. The V(1)-Mn(1) bond length is 3.25 Å. The V(1)-Sn(2) bond length is 0.44 Å. Mn(1) is bonded in a 8-coordinate geometry to one V(1), six equivalent Mn(1), and one Sn(1) atom. All Mn(1)-Mn(1) bond lengths are 3.09 Å. The Mn(1)-Sn(1) bond length is 3.68 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Mn(1) and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.24 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one V(1) and one Sn(1) atom.
