Cr In Ga Ga
CrInGa2 crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a 1-coordinate geometry to one In(1) and three equivalent Ga(1) atoms. The Cr(1)-In(1) bond length is 0.74 Å. There is one shorter (1.92 Å) and two longer (2.93 Å) Cr(1)-Ga(1) bond lengths. In(1) is bonded in a single-bond geometry to one Cr(1) and one Ga(2) atom. The In(1)-Ga(2) bond length is 2.48 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to three equivalent Cr(1) and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 1.64 Å. In the second Ga site, Ga(2) is bonded in a distorted bent 150 degrees geometry to one In(1) and one Ga(1) atom.
