The compound described by AgZnSmP2 crystallizes in the trigonal P3m1 space group. Sm(1) is bonded to three equivalent P(1) and three equivalent P(2) atoms to form distorted SmP6 octahedra that share corners with six equivalent Zn(1)P4 tetrahedra, edges with six equivalent Sm(1)P6 octahedra, and edges with three equivalent Zn(1)P4 tetrahedra. Ag(1) is bonded in a 4-coordinate geometry to one P(1) and three equivalent P(2) atoms. Zn(1) is bonded to one P(2) and three equivalent P(1) atoms to form distorted ZnP4 tetrahedra that share corners with six equivalent Sm(1)P6 octahedra, corners with six equivalent Zn(1)P4 tetrahedra, and edges with three equivalent Sm(1)P6 octahedra. The corner-sharing octahedral tilt angles range from 17-57°. There are two inequivalent P sites. In the first P site, P(1) is bonded to three equivalent Sm(1), one Ag(1), and three equivalent Zn(1) atoms to form distorted PSm3Zn3Ag pentagonal bipyramids that share corners with three equivalent P(2)Sm3ZnAg3 pentagonal bipyramids, edges with six equivalent P(1)Sm3Zn3Ag pentagonal bipyramids, and edges with six equivalent P(2)Sm3ZnAg3 pentagonal bipyramids. In the second P site, P(2) is bonded to three equivalent Sm(1), three equivalent Ag(1), and one Zn(1) atom to form distorted PSm3ZnAg3 pentagonal bipyramids that share corners with three equivalent P(1)Sm3Zn3Ag pentagonal bipyramids, edges with six equivalent P(1)Sm3Zn3Ag pentagonal bipyramids, and edges with six equivalent P(2)Sm3ZnAg3 pentagonal bipyramids. is represented by the CIF file [CIF]
