Zn Zn Cr Cl
CrZn2Cl crystallizes in the triclinic P1 space group. Cr(1) is bonded in a 2-coordinate geometry to one Zn(1) and one Cl(1) atom. The Cr(1)-Zn(1) bond length is 2.37 Å. The Cr(1)-Cl(1) bond length is 2.36 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one Cr(1), one Zn(2), four equivalent Zn(1), and one Cl(1) atom to form a mixture of distorted corner and edge-sharing ZnZn5CrCl pentagonal bipyramids. The Zn(1)-Zn(2) bond length is 2.62 Å. All Zn(1)-Zn(1) bond lengths are 3.08 Å. The Zn(1)-Cl(1) bond length is 2.63 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one Zn(1) and one Cl(1) atom. The Zn(2)-Cl(1) bond length is 0.06 Å. Cl(1) is bonded in a single-bond geometry to one Cr(1), one Zn(1), and one Zn(2) atom.
