CeAgZnP2 crystallizes in the trigonal P3m1 space group. Ce(1) is bonded to three equivalent P(1) and three equivalent P(2) atoms to form CeP6 octahedra that share corners with six equivalent Ag(1)P4 tetrahedra, corners with six equivalent Zn(1)P4 tetrahedra, edges with six equivalent Ce(1)P6 octahedra, edges with three equivalent Ag(1)P4 tetrahedra, and edges with three equivalent Zn(1)P4 tetrahedra. Ag(1) is bonded to one P(1) and three equivalent P(2) atoms to form distorted AgP4 tetrahedra that share corners with six equivalent Ce(1)P6 octahedra, corners with six equivalent Ag(1)P4 tetrahedra, edges with three equivalent Ce(1)P6 octahedra, and edges with three equivalent Zn(1)P4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-55°. 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 Ce(1)P6 octahedra, corners with six equivalent Zn(1)P4 tetrahedra, edges with three equivalent Ce(1)P6 octahedra, and edges with three equivalent Ag(1)P4 tetrahedra. The corner-sharing octahedral tilt angles range from 17-56°. There are two inequivalent P sites. In the first P site, P(1) is bonded to three equivalent Ce(1), one Ag(1), and three equivalent Zn(1) atoms to form distorted PCe3Zn3Ag pentagonal bipyramids that share corners with three equivalent P(2)Ce3ZnAg3 pentagonal bipyramids, edges with six equivalent P(1)Ce3Zn3Ag pentagonal bipyramids, and edges with six equivalent P(2)Ce3ZnAg3 pentagonal bipyramids. In the second P site, P(2) is bonded to three equivalent Ce(1), three equivalent Ag(1), and one Zn(1) atom to form distorted PCe3ZnAg3 pentagonal bipyramids that share corners with three equivalent P(1)Ce3Zn3Ag pentagonal bipyramids, edges with six equivalent P(1)Ce3Zn3Ag pentagonal bipyramids, and edges with six equivalent P(2)Ce3ZnAg3 pentagonal bipyramids.
