K2Pt(N2O5)2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 9-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent N(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(1), and one O(2) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one Pt(1), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1) and one N(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent K(1) and one N(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent K(1) and one O(5) atom.
