The material structure described by SmCo5P3 crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 17-coordinate geometry to one Co(1), one Co(5), three equivalent Co(2), three equivalent Co(3), three equivalent Co(4), two equivalent P(1), two equivalent P(2), and two equivalent P(3) atoms. There are five inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to one Sm(1), one P(3), two equivalent P(1), and two equivalent P(2) atoms. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to three equivalent Sm(1), one P(2), and three equivalent P(3) atoms. In the third Co site, Co(3) is bonded to three equivalent Sm(1), one P(1), one P(2), and two equivalent P(3) atoms to form distorted CoSm3P4 tetrahedra that share  a cornercorner with one Co(5)SmP4 tetrahedra, corners with three equivalent Co(4)Sm3P4 tetrahedra, corners with four equivalent Co(3)Sm3P4 tetrahedra, edges with two equivalent Co(3)Sm3P4 tetrahedra, edges with three equivalent Co(5)SmP4 tetrahedra, and faces with three equivalent Co(4)Sm3P4 tetrahedra. In the fourth Co site, Co(4) is bonded to three equivalent Sm(1), one P(1), one P(3), and two equivalent P(2) atoms to form distorted CoSm3P4 tetrahedra that share corners with two equivalent Co(5)SmP4 tetrahedra, corners with three equivalent Co(3)Sm3P4 tetrahedra, corners with four equivalent Co(4)Sm3P4 tetrahedra, edges with two equivalent Co(4)Sm3P4 tetrahedra, faces with two equivalent Co(5)SmP4 tetrahedra, and faces with three equivalent Co(3)Sm3P4 tetrahedra. In the fifth Co site, Co(5) is bonded to one Sm(1), one P(2), and three equivalent P(1) atoms to form distorted CoSmP4 tetrahedra that share  a cornercorner with one Co(3)Sm3P4 tetrahedra, corners with two equivalent Co(4)Sm3P4 tetrahedra, corners with two equivalent Co(5)SmP4 tetrahedra, edges with two equivalent Co(5)SmP4 tetrahedra, edges with three equivalent Co(3)Sm3P4 tetrahedra, and faces with two equivalent Co(4)Sm3P4 tetrahedra. There are three inequivalent P sites. In the first P site, P(3) is bonded in a 9-coordinate geometry to two equivalent Sm(1), one Co(1), one Co(4), two equivalent Co(3), and three equivalent Co(2) atoms. In the second P site, P(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), one Co(3), one Co(4), two equivalent Co(1), and three equivalent Co(5) atoms. In the third P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Sm(1), one Co(2), one Co(3), one Co(5), two equivalent Co(1), and two equivalent Co(4) atoms. is represented by the CIF file [CIF]
