The material structure described by HfCoGa crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to one Co(2), four equivalent Co(1), and six equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Ga(1) atoms. In the second Co site, Co(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Hf(1), two equivalent Co(1), and two equivalent Co(2) atoms. is represented by the CIF card [CIF]
