V Re Sb Sb
VReSb2 crystallizes in the monoclinic Cm space group. V(1) is bonded in a 4-coordinate geometry to one Re(1) and three equivalent Sb(1) atoms. The V(1)-Re(1) bond length is 2.08 Å. There is one shorter (1.71 Å) and two longer (2.39 Å) V(1)-Sb(1) bond lengths. Re(1) is bonded in a distorted single-bond geometry to one V(1) and one Sb(2) atom. The Re(1)-Sb(2) bond length is 2.80 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 1-coordinate geometry to three equivalent V(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 2.17 Å. In the second Sb site, Sb(2) is bonded in a 2-coordinate geometry to one Re(1) and one Sb(1) atom.
