The material described by KUN3O11 crystallizes in the monoclinic C2/c space group. K(1) is bonded to two equivalent O(2), two equivalent O(3), two equivalent O(5), two equivalent O(6), and four equivalent O(1) atoms to form distorted corner-sharing KO12 cuboctahedra. U(1) is bonded in a distorted linear geometry to two equivalent O(4) and two equivalent O(5) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(6) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded in a 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 one K(1) and one N(1) atom. In the fourth O site, O(4) is bonded in a distorted L-shaped geometry to one U(1) and one N(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(1) and one U(1) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one K(1) and one N(1) atom. is represented by the CIF file [CIF]
