KC(NO2)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. C(1) is bonded in a distorted trigonal planar geometry to one C(1), one N(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one C(1), one O(1), and one O(4) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent K(1) and one N(1) atom.
