The material structure described by Mg3Tb2Ni2 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to four equivalent Mg(2) and one Ni(1) atom. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to eight equivalent Mg(1) and two equivalent Tb(1) atoms. Tb(1) is bonded in a 6-coordinate geometry to one Mg(2) and six equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to one Mg(1), six equivalent Tb(1), and two equivalent Ni(1) atoms. is represented by the CIF file [CIF]
