Na In In Ga
NaIn2Ga is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaIn2Ga clusters. Na(1) is bonded in a 3-coordinate geometry to two equivalent In(1) and one Ga(1) atom. Both Na(1)-In(1) bond lengths are 1.92 Å. The Na(1)-Ga(1) bond length is 1.88 Å. In(1) is bonded in a 1-coordinate geometry to one Na(1) atom. Ga(1) is bonded in a distorted single-bond geometry to one Na(1) atom.
