The Materials Project

K4BeP2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a trigonal non-coplanar geometry to three equivalent P3- atoms. All K–P bond lengths are 3.35 Å. In the second K1+ site, K1+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing KP4 tetrahedra. There are one shorter (3.28 Å) and three longer (3.43 Å) K–P bond lengths. Be2+ is bonded in a linear geometry to two equivalent P3- atoms. Both Be–P bond lengths are 2.00 Å. P3- is bonded in a distorted single-bond geometry to seven K1+ and one Be2+ atom.
