V Zn B B
VZnB2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VZnB2 clusters. V(1) is bonded in a distorted single-bond geometry to one B(1) atom. The V(1)-B(1) bond length is 2.14 Å. Zn(1) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom. The Zn(1)-B(1) bond length is 1.26 Å. The Zn(1)-B(2) bond length is 1.26 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted single-bond geometry to one V(1) and one Zn(1) atom. In the second B site, B(2) is bonded in a single-bond geometry to one Zn(1) atom.
