The crystal structure described by HfCoSn crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 7-coordinate geometry to six equivalent Co(1), one Sn(2), and four equivalent Sn(1) atoms. Co(1) is bonded in a 12-coordinate geometry to six equivalent Hf(1), two equivalent Co(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Co(1) atoms. In the second Sn site, Sn(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Co(1) atoms. is represented by the CIF card [CIF]
