Be In In Ga
BeIn2Ga crystallizes in the monoclinic Cm space group. Be(1) is bonded in a single-bond geometry to three equivalent In(2) and one Ga(1) atom. There is one shorter (2.93 Å) and two longer (3.17 Å) Be(1)-In(2) bond lengths. The Be(1)-Ga(1) bond length is 0.19 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 8-coordinate geometry to one In(2), four equivalent In(1), and three equivalent Ga(1) atoms. The In(1)-In(2) bond length is 3.21 Å. All In(1)-In(1) bond lengths are 3.15 Å. There is one shorter (3.07 Å) and two longer (3.31 Å) In(1)-Ga(1) bond lengths. In the second In site, In(2) is bonded in a 8-coordinate geometry to three equivalent Be(1), one In(1), and four equivalent In(2) atoms. All In(2)-In(2) bond lengths are 3.15 Å. Ga(1) is bonded in a single-bond geometry to one Be(1) and three equivalent In(1) atoms.
