Ca2PdP4O8 crystallizes in the orthorhombic Fddd space group. Ca(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. Pd(1) is bonded in a distorted trigonal pyramidal geometry to four equivalent P(1) atoms. P(1) is bonded in a water-like geometry to one Pd(1), one O(1), and one O(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to one Ca(1) and one P(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Ca(1) and one P(1) atom.
