Nb Zn As
NbZnAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbZnAs clusters. Nb(1) is bonded in a single-bond geometry to one Zn(1) atom. The Nb(1)-Zn(1) bond length is 1.23 Å. Zn(1) is bonded in a distorted single-bond geometry to one Nb(1) and one As(1) atom. The Zn(1)-As(1) bond length is 0.28 Å. As(1) is bonded in a single-bond geometry to one Zn(1) atom.
