K4ZnP2 crystallizes in the trigonal R-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent P(1) atoms to form a mixture of edge and corner-sharing KP4 tetrahedra. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent Zn(1) and three equivalent P(1) atoms. Zn(1) is bonded in a linear geometry to six equivalent K(2) and two equivalent P(1) atoms. P(1) is bonded in a distorted body-centered cubic geometry to three equivalent K(2), four equivalent K(1), and one Zn(1) atom.
K4ZnP2 crystallizes in the trigonal R-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent P(1) atoms to form a mixture of edge and corner-sharing KP4 tetrahedra. There is one shorter (3.24 Å) and three longer (3.42 Å) K(1)-P(1) bond lengths. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent Zn(1) and three equivalent P(1) atoms. All K(2)-Zn(1) bond lengths are 3.53 Å. All K(2)-P(1) bond lengths are 3.36 Å. Zn(1) is bonded in a linear geometry to six equivalent K(2) and two equivalent P(1) atoms. Both Zn(1)-P(1) bond lengths are 2.20 Å. P(1) is bonded in a distorted body-centered cubic geometry to three equivalent K(2), four equivalent K(1), and one Zn(1) atom.
