K2RuNOBr5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent Br(1), two equivalent Br(2), two equivalent Br(4), and three equivalent Br(3) atoms. Ru(1) is bonded in a distorted octahedral geometry to one N(1), one Br(1), one Br(2), one Br(4), and two equivalent Br(3) 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 Br sites. In the first Br site, Br(1) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of distorted corner, face, and edge-sharing BrK4Ru square pyramids. In the second Br site, Br(2) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of distorted corner, face, and edge-sharing BrK4Ru square pyramids. In the third Br site, Br(3) is bonded in a 3-coordinate geometry to three equivalent K(1) and one Ru(1) atom. In the fourth Br site, Br(4) is bonded to four equivalent K(1) and one Ru(1) atom to form a mixture of distorted corner, face, and edge-sharing BrK4Ru square pyramids.
