The structure described by HoP5 crystallizes in the monoclinic P2_1/m space group. Ho(1) is bonded in a 8-coordinate geometry to two equivalent P(1), two equivalent P(2), and four equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(3) is bonded to two equivalent Ho(1), one P(2), and one P(3) atom to form PHo2P2 tetrahedra that share corners with four equivalent P(3)Ho2P2 tetrahedra, corners with five equivalent P(1)Ho2P2 tetrahedra, corners with six equivalent P(2)HoP3 tetrahedra, and  an edgeedge with one P(3)Ho2P2 tetrahedra. In the second P site, P(1) is bonded to two equivalent Ho(1) and two equivalent P(2) atoms to form distorted PHo2P2 tetrahedra that share corners with two equivalent P(1)Ho2P2 tetrahedra, corners with six equivalent P(2)HoP3 tetrahedra, and corners with ten equivalent P(3)Ho2P2 tetrahedra. In the third P site, P(2) is bonded to one Ho(1), one P(1), one P(2), and one P(3) atom to form distorted PHoP3 tetrahedra that share corners with three equivalent P(1)Ho2P2 tetrahedra, corners with six equivalent P(3)Ho2P2 tetrahedra, and  an edgeedge with one P(2)HoP3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
