KNO3 is Calcite-like structured and crystallizes in the trigonal R32 space group. K(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing KO6 octahedra. The corner-sharing octahedral tilt angles are 67°. N(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent K(1) and one N(1) atom.
