The material described by Zr2Cu crystallizes in the monoclinic C2/m space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 5-coordinate geometry to five equivalent Cu(1) atoms. In the second Zr site, Zr(2) is bonded in a 2-coordinate geometry to three equivalent Cu(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to three equivalent Zr(2), five equivalent Zr(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
