The material described by Ho2Co12P7 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 12-coordinate geometry to six equivalent Co(4) and six equivalent P(3) atoms. In the second Ho site, Ho(2) is bonded in a 18-coordinate geometry to three equivalent Co(1), three equivalent Co(4), six equivalent Co(2), and six equivalent P(2) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to one Ho(2), one P(1), one P(3), and two equivalent P(2) atoms to form distorted CoHoP4 tetrahedra that share corners with two equivalent Co(2)Ho2P4 tetrahedra, corners with six equivalent Co(1)HoP4 tetrahedra, edges with two equivalent Co(2)Ho2P4 tetrahedra, and faces with two equivalent Co(2)Ho2P4 tetrahedra. In the second Co site, Co(2) is bonded to two equivalent Ho(2), two equivalent P(2), and two equivalent P(3) atoms to form distorted CoHo2P4 tetrahedra that share corners with two equivalent Co(1)HoP4 tetrahedra, corners with four equivalent Co(2)Ho2P4 tetrahedra, edges with two equivalent Co(2)Ho2P4 tetrahedra, edges with two equivalent Co(1)HoP4 tetrahedra, faces with two equivalent Co(2)Ho2P4 tetrahedra, and faces with two equivalent Co(1)HoP4 tetrahedra. In the third Co site, Co(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 Co site, Co(4) is bonded in a 4-coordinate geometry to one Ho(2), two equivalent Ho(1), 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 Co(1) and six equivalent Co(3) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), one Co(3), two equivalent Co(1), two equivalent Co(2), and two equivalent Co(4) atoms. In the third P site, P(3) is bonded in a 9-coordinate geometry to two equivalent Ho(1), one Co(1), two equivalent Co(2), two equivalent Co(3), and two equivalent Co(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
