CoZnAl2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CoZnAl2 clusters. Co(1) is bonded in a single-bond geometry to one Al(1) atom. The Co(1)-Al(1) bond length is 1.51 Å. Zn(1) is bonded in a distorted single-bond geometry to one Al(2) atom. The Zn(1)-Al(2) bond length is 2.13 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a linear geometry to one Co(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 1.28 Å. In the second Al site, Al(2) is bonded in a distorted linear geometry to one Zn(1) and one Al(1) atom.
