Materials Data on Sm(CoP)2 by Materials Project
SmCo2P2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm3+ is bonded in a distorted body-centered cubic geometry to eight equivalent P3- atoms. All Sm–P bond lengths are 3.01 Å. Co+1.50+ is bonded to four equivalent P3- atoms to form a mixture of corner and edge-sharing CoP4 tetrahedra. All Co–P bond lengths are 2.25 Å. P3- is bonded in a 9-coordinate geometry to four equivalent Sm3+, four equivalent Co+1.50+, and one P3- atom. The P–P bond length is 2.51 Å.
