The crystal structure described by Na2ZnB6O11 crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 7-coordinate geometry to one O(1), one O(4), one O(6), two equivalent O(2), and two equivalent O(3) atoms. Zn(1) is bonded in a trigonal planar geometry to one O(5) and two equivalent O(6) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(4) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(2), one O(4), and one O(6) atom. In the third B site, B(3) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form corner-sharing BO4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Na(1), one B(1), and one B(3) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Na(1), one B(2), and one B(3) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Na(1), one B(1), and one B(3) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Na(1), one B(1), and one B(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Zn(1) and two equivalent B(3) atoms. In the sixth O site, O(6) is bonded in a 2-coordinate geometry to one Na(1), one Zn(1), and one B(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
