The material structure described by KUCrNO9 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(3), one O(6), one O(7), one O(8), one O(9), and two equivalent O(4) atoms. U(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom to form distorted UO7 pentagonal bipyramids that share corners with three equivalent Cr(1)O4 tetrahedra. Cr(1) is bonded to one O(2), one O(3), one O(5), and one O(8) atom to form CrO4 tetrahedra that share corners with three equivalent U(1)O7 pentagonal bipyramids. N(1) is bonded in a trigonal planar geometry to one O(6), one O(7), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a distorted bent 150 degrees geometry to one U(1) and one Cr(1) atom. In the second O site, O(6) is bonded in a distorted single-bond geometry to one K(1), one U(1), and one N(1) atom. In the third O site, O(7) is bonded in a distorted single-bond geometry to one K(1), one U(1), and one N(1) atom. In the fourth O site, O(8) is bonded in a distorted single-bond geometry to one K(1) and one Cr(1) atom. In the fifth O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one U(1) atom. In the sixth O site, O(9) is bonded in a distorted single-bond geometry to one K(1) and one N(1) atom. In the seventh O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one U(1), and one Cr(1) atom. In the eighth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1), one U(1), and one Cr(1) atom.
