The material described by Bi2Mg crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 10-coordinate geometry to ten equivalent Bi(1) atoms. Bi(1) is bonded to five equivalent Mg(1) and seven equivalent Bi(1) atoms to form a mixture of distorted edge, corner, and face-sharing BiMg5Bi7 cuboctahedra. is represented by the CIF card [CIF]
