Y Y Zr Zr Sb Sb
YZrSb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of four stibanylidyneyttrium molecules and two Zr clusters. In each Zr cluster, Zr(1) is bonded in a distorted single-bond geometry to one Zr(1) atom. The Zr(1)-Zr(1) bond length is 0.86 Å.
