KPtN2O5 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. Pt(1) is bonded in a square co-planar geometry to one N(1), one N(2), and two equivalent O(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Pt(1), one O(3), and one O(5) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one Pt(1), one O(1), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(2) atom. In the third O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one K(1) and two equivalent Pt(1) atoms.
