The material structure described by Mg2Cu is Khatyrkite structured and crystallizes in the orthorhombic Ibam space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent Cu(1) atoms. Cu(1) is bonded in a 10-coordinate geometry to eight equivalent Mg(1) and two equivalent Cu(1) atoms. is represented by the CIF file [CIF]
