The structure described by KZn4B3O9 crystallizes in the monoclinic P2/c space group. K(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form corner-sharing ZnO4 tetrahedra. In the second Zn site, Zn(2) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form corner-sharing ZnO4 tetrahedra. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(5) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(3) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Zn(1), one Zn(2), and one B(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one K(1), one Zn(2), and one B(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Zn(1), one Zn(2), and one B(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one B(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Zn(1), one Zn(2), and one B(1) atom. is represented by the CIF file [CIF]
