KAu(NO3)4 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a hexagonal bipyramidal geometry to two equivalent O(2), two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms. Au(1) is bonded in a square co-planar geometry to two equivalent O(4) and two equivalent O(6) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one O(2), 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(1), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one N(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one K(1) and one N(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one K(1) and one N(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Au(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 N(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one K(1), one Au(1), and one N(1) atom.
