K2Cd(C2O5)2 crystallizes in the orthorhombic Fdd2 space group. K(1) is bonded in a 9-coordinate geometry to one O(1), one O(3), two equivalent O(2), two equivalent O(4), and three equivalent O(5) atoms. Cd(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(4) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. There are five inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one K(1), one Cd(1), and one C(2) atom. In the second O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1), one Cd(1), and one C(1) atom. In the third O site, O(5) is bonded in a T-shaped geometry to three equivalent K(1) atoms. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), one Cd(1), and one C(2) atom. In the fifth O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one Cd(1), and one C(1) atom.
