Materials Data on MgGaAu2 by Materials Project

MgAu2Ga crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mg is bonded in a 8-coordinate geometry to eight equivalent Au atoms. There are six shorter (2.93 Å) and two longer (2.95 Å) Mg–Au bond lengths. Au is bonded in a 7-coordinate geometry to four equivalent Mg and three equivalent Ga atoms. All Au–Ga bond lengths are 2.69 Å. Ga is bonded in a distorted hexagonal planar geometry to six equivalent Au atoms.

Materials Data on MgGaAu2 by Materials Project

MgAu2Ga crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two MgAu2Ga ribbons oriented in the (1, 0, 0) direction. Mg is bonded in a linear geometry to two equivalent Au atoms. Both Mg–Au bond lengths are 2.60 Å. Au is bonded in a linear geometry to one Mg and one Ga atom. The Au–Ga bond length is 2.49 Å. Ga is bonded in a linear geometry to two equivalent Au atoms.
