The structure described by HfPt2Al crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 11-coordinate geometry to eight equivalent Pt(1) and three equivalent Al(1) atoms. Pt(1) is bonded in a 11-coordinate geometry to four equivalent Hf(1), four equivalent Pt(1), and three equivalent Al(1) atoms. Al(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Pt(1) atoms. is represented by the CIF card [CIF]
