The crystal structure described by KNa2BO3 crystallizes in the orthorhombic Pmmn space group. K(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Na(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one K(1), four equivalent Na(1), and one B(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent K(1), two equivalent Na(1), and one B(1) atom. is represented by the CIF file [CIF]
