PdZnP2O7 crystallizes in the orthorhombic Pnma space group. Pd(1) is bonded in a square co-planar geometry to two equivalent O(4) and two equivalent O(5) atoms. Zn(1) is bonded to one O(1), one O(3), two equivalent O(4), and two equivalent O(5) atoms to form ZnO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(3), and two equivalent O(5) atoms to form PO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-56°. In the second P site, P(2) is bonded to one O(1), one O(2), and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 29-58°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a trigonal planar geometry to one Pd(1), one Zn(1), and one P(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(3) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(1) atom. In the fifth O site, O(4) is bonded in a distorted trigonal planar geometry to one Pd(1), one Zn(1), and one P(2) atom.
