The compound described by K2PdP2O7 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to one O(4), two equivalent O(1), and four equivalent O(3) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(4), two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Pd(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing PO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one P(1) atom. In the second O site, O(4) is bonded in a distorted bent 150 degrees geometry to one K(1), one K(2), and two equivalent P(1) atoms. In the third O site, O(1) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Pd(1), and one P(1) atom. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(2), one Pd(1), and one P(1) atom. is represented by the CIF card [CIF]
