The material structure described by Ho2Ni12P7 crystallizes in the hexagonal P-6 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 18-coordinate geometry to three equivalent Ni(2), three equivalent Ni(4), six equivalent Ni(1), and six equivalent P(2) atoms. In the second Ho site, Ho(2) is bonded in a 15-coordinate geometry to three equivalent Ni(1), six equivalent Ni(4), and six equivalent P(3) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to one Ho(2), two equivalent Ho(1), two equivalent P(2), and two equivalent P(3) atoms to form distorted NiHo3P4 tetrahedra that share corners with two equivalent Ni(2)HoP4 tetrahedra, corners with six equivalent Ni(1)Ho3P4 tetrahedra, edges with two equivalent Ni(1)Ho3P4 tetrahedra, edges with two equivalent Ni(2)HoP4 tetrahedra, faces with two equivalent Ni(1)Ho3P4 tetrahedra, and faces with two equivalent Ni(2)HoP4 tetrahedra. In the second Ni site, Ni(2) is bonded to one Ho(1), one P(1), one P(3), and two equivalent P(2) atoms to form distorted NiHoP4 tetrahedra that share corners with two equivalent Ni(1)Ho3P4 tetrahedra, corners with six equivalent Ni(2)HoP4 tetrahedra, edges with two equivalent Ni(1)Ho3P4 tetrahedra, and faces with two equivalent Ni(1)Ho3P4 tetrahedra. In the third Ni site, Ni(3) is bonded in a 5-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(3) atoms. In the fourth Ni site, Ni(4) is bonded in a 4-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent P(2), and two equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to three equivalent Ni(2) and six equivalent Ni(3) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), one Ni(3), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Ni(4) atoms. In the third P site, P(3) is bonded in a 9-coordinate geometry to two equivalent Ho(2), one Ni(2), two equivalent Ni(1), two equivalent Ni(3), and two equivalent Ni(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
