In the first N site, N(1) is bonded in a 4-coordinate geometry to one K(1), one Pt(1), one O(1), and one O(2) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Pt(1), one O(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 one K(1), one N(1), and one N(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one N(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one K(1) and one N(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one 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.
