The material structure described by Zr2Cu2Al crystallizes in the orthorhombic Cmmm space group. Zr(1) is bonded in a 13-coordinate geometry to three equivalent Zr(1), six equivalent Cu(1), and four equivalent Al(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Zr(1), two equivalent Cu(1), and one Al(1) atom. Al(1) is bonded in a 2-coordinate geometry to eight equivalent Zr(1) and two equivalent Cu(1) atoms. is represented by the CIF file [CIF]
