The material described by MgZn2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 9-coordinate geometry to four equivalent Zn(2) and five equivalent Zn(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 7-coordinate geometry to five equivalent Mg(1) and two equivalent Zn(2) atoms. In the second Zn site, Zn(2) is bonded in a 8-coordinate geometry to four equivalent Mg(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
