The crystal structure described by (HfAs)2CuSi is Indium-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one 7440-21-3 atom, one 7440-50-8 atom, and two HfAs clusters. In each HfAs cluster, Hf(1) is bonded in a single-bond geometry to one As(1) atom. As(1) is bonded in a single-bond geometry to one Hf(1) atom. is represented by the CIF card [CIF]
