The compound described by Li2CeP2 crystallizes in the trigonal P-3m1 space group. Li(1) is bonded to four equivalent P(1) atoms to form LiP4 tetrahedra that share corners with six equivalent Ce(1)P6 octahedra, corners with six equivalent Li(1)P4 tetrahedra, edges with three equivalent Ce(1)P6 octahedra, and edges with three equivalent Li(1)P4 tetrahedra. The corner-sharing octahedral tilt angles range from 10-57°. Ce(1) is bonded to six equivalent P(1) atoms to form CeP6 octahedra that share corners with twelve equivalent Li(1)P4 tetrahedra, edges with six equivalent Ce(1)P6 octahedra, and edges with six equivalent Li(1)P4 tetrahedra. P(1) is bonded to four equivalent Li(1) and three equivalent Ce(1) atoms to form a mixture of distorted corner and edge-sharing PLi4Ce3 pentagonal bipyramids. is represented by the CIF card [CIF]
