The structure described by BaMg3 crystallizes in the orthorhombic Pmm2 space group. Ba(1) is bonded to two equivalent Ba(1), two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms to form a mixture of distorted corner, face, and edge-sharing BaBa2Mg10 cuboctahedra. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Mg(1), and two equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
