Zn Re Re Sb
Re2ZnSb crystallizes in the monoclinic Cm space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a single-bond geometry to one Re(2) and one Sb(1) atom. The Re(1)-Re(2) bond length is 2.37 Å. The Re(1)-Sb(1) bond length is 0.73 Å. In the second Re site, Re(2) is bonded in a 2-coordinate geometry to one Re(1) and one Zn(1) atom. The Re(2)-Zn(1) bond length is 2.86 Å. Zn(1) is bonded in a 5-coordinate geometry to one Re(2) and four equivalent Sb(1) atoms. There are a spread of Zn(1)-Sb(1) bond distances ranging from 2.13-3.02 Å. Sb(1) is bonded in a distorted single-bond geometry to one Re(1) and four equivalent Zn(1) atoms.
