K2RuNOI5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent I(1), two equivalent I(3), two equivalent I(4), and three equivalent I(2) atoms. Ru(1) is bonded in a distorted single-bond geometry to one N(1), one I(1), one I(3), one I(4), and two equivalent I(2) atoms. N(1) is bonded in a linear geometry to one Ru(1) and one O(1) atom. O(1) is bonded in a single-bond geometry to one N(1) atom. There are four inequivalent I sites. In the first I site, I(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Ru(1) atom. In the second I site, I(2) is bonded in a 3-coordinate geometry to three equivalent K(1) and one Ru(1) atom. In the third I site, I(3) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of distorted corner, edge, and face-sharing IK4Ru square pyramids. In the fourth I site, I(4) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of corner, edge, and face-sharing IK4Ru square pyramids.
