MgCu2(PdO2)2 crystallizes in the monoclinic P2 space group. Mg(1) is bonded in a 3-coordinate geometry to one O(3) and two equivalent O(4) atoms. Pd(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. Cu(1) is bonded in a bent 150 degrees geometry to one O(1) and one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Cu(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Cu(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Pd(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Pd(1) atoms.
