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 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent K(1), one Zn(2), 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 to four equivalent K(1) and two equivalent Zn(2) atoms to form distorted edge-sharing OK4Zn2 octahedra.
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. Both K(1)-O(2) bond lengths are 3.03 Å. There is one shorter (2.72 Å) and one longer (2.75 Å) K(1)-O(3) bond length. All K(1)-O(1) bond lengths are 2.90 Å. 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. The Zn(1)-O(2) bond length is 2.03 Å. There is one shorter (1.94 Å) and two longer (1.97 Å) Zn(1)-O(1) bond lengths.
