Materials Data on Li2CuP by Materials Project
Li2CuP crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li1+ is bonded to four equivalent P3- atoms to form a mixture of distorted face, edge, and corner-sharing LiP4 tetrahedra. There are one shorter (2.58 Å) and three longer (2.65 Å) Li–P bond lengths. Cu1+ is bonded in a trigonal planar geometry to three equivalent P3- atoms. All Cu–P bond lengths are 2.33 Å. P3- is bonded in a 11-coordinate geometry to eight equivalent Li1+ and three equivalent Cu1+ atoms.
