Materials Data on CsNiP by Materials Project
CsNiP crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Cs1+ is bonded in a rectangular see-saw-like geometry to four equivalent P3- atoms. There are two shorter (3.44 Å) and two longer (3.58 Å) Cs–P bond lengths. Ni2+ is bonded in a linear geometry to two equivalent P3- atoms. Both Ni–P bond lengths are 2.11 Å. P3- is bonded to four equivalent Cs1+ and two equivalent Ni2+ atoms to form a mixture of distorted corner and edge-sharing PCs4Ni2 octahedra. The corner-sharing octahedra tilt angles range from 0–80°.
