ReZn2Al crystallizes in the monoclinic Cm space group. Re(1) is bonded in a 2-coordinate geometry to one Zn(2) and four equivalent Al(1) atoms. The Re(1)-Zn(2) bond length is 1.38 Å. There are a spread of Re(1)-Al(1) bond distances ranging from 2.06-3.14 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one Zn(2) and one Al(1) atom. The Zn(1)-Zn(2) bond length is 2.00 Å. The Zn(1)-Al(1) bond length is 1.94 Å. In the second Zn site, Zn(2) is bonded in a distorted single-bond geometry to one Re(1) and one Zn(1) atom. Al(1) is bonded in a 5-coordinate geometry to four equivalent Re(1) and one Zn(1) atom.
