The material described by K2Zn6O7 crystallizes in the tetragonal P4_2nm space group. K(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(2) and three equivalent O(1) atoms to form corner-sharing ZnO4 tetrahedra. In the second Zn site, Zn(2) is bonded in a distorted trigonal planar geometry to one O(3) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and three equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to four equivalent K(1) and two equivalent Zn(2) atoms. is represented by the CIF file [CIF]
