The compound described by KZn(BO2)3 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 9-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms. Zn(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with two equivalent B(3)O4 tetrahedra and  an edgeedge with one Zn(1)O4 tetrahedra. There are three inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(2), one O(5), and one O(6) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(6) atom.
