The material described by ErGa2(Ga)4 is Indium-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of two ErGa2 clusters and two Ga clusters. In each ErGa2 cluster, Er(1) is bonded in a linear geometry to two equivalent Ga(2) atoms. Ga(2) is bonded in a single-bond geometry to one Er(1) atom. In each Ga cluster, Ga(1) is bonded in an L-shaped geometry to two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
