The material structure described by Hf9W4P crystallizes in the orthorhombic Cmcm space group. There are four inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 5-coordinate geometry to one W(1), one W(3), two equivalent W(2), and one P(1) atom. In the second Hf site, Hf(2) is bonded in a 6-coordinate geometry to one Hf(2), two equivalent Hf(4), two equivalent W(2), and one P(1) atom. In the third Hf site, Hf(3) is bonded in a single-bond geometry to one P(1) atom. In the fourth Hf site, Hf(4) is bonded in a distorted linear geometry to four equivalent Hf(2), one W(1), and one W(2) atom. There are three inequivalent W sites. In the first W site, W(1) is bonded in a 4-coordinate geometry to two equivalent Hf(1) and two equivalent Hf(4) atoms. In the second W site, W(2) is bonded in a 7-coordinate geometry to one Hf(4), two equivalent Hf(1), and four equivalent Hf(2) atoms. In the third W site, W(3) is bonded in a linear geometry to two equivalent Hf(1) atoms. P(1) is bonded in a 7-coordinate geometry to one Hf(3), two equivalent Hf(1), and four equivalent Hf(2) atoms. is represented by the CIF card [CIF]
