The compound described by HfP2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent P(1) and five equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 5-coordinate geometry to five equivalent Hf(1) and two equivalent P(1) atoms. In the second P site, P(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1), two equivalent P(1), and two equivalent P(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
