The compound described by LaMg2Ni crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ni(1) atoms. La(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent La(1) atoms. is represented by the CIF file [CIF]
