Y Mg In Ga
MgYInGa crystallizes in the trigonal R3m space group. Mg(1) is bonded in a 10-coordinate geometry to three equivalent Y(1), four equivalent In(1), and three equivalent Ga(1) atoms. All Mg(1)-Y(1) bond lengths are 3.07 Å. There is one shorter (2.54 Å) and three longer (3.35 Å) Mg(1)-In(1) bond lengths. All Mg(1)-Ga(1) bond lengths are 3.01 Å. Y(1) is bonded in a distorted linear geometry to three equivalent Mg(1), one In(1), and four equivalent Ga(1) atoms. The Y(1)-In(1) bond length is 2.54 Å. There is one shorter (2.54 Å) and three longer (3.35 Å) Y(1)-Ga(1) bond lengths. In(1) is bonded in a linear geometry to four equivalent Mg(1), one Y(1), and three equivalent Ga(1) atoms. All In(1)-Ga(1) bond lengths are 3.07 Å. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Mg(1), four equivalent Y(1), and three equivalent In(1) atoms.
