The structure described by NaCdPO4 crystallizes in the orthorhombic Pna2_1 space group. Na(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form NaO6 octahedra that share corners with four equivalent Cd(1)O6 pentagonal pyramids, corners with two equivalent P(1)O4 tetrahedra, edges with two equivalent Na(1)O6 octahedra, edges with two equivalent Cd(1)O6 pentagonal pyramids, and edges with two equivalent P(1)O4 tetrahedra. Cd(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted CdO6 pentagonal pyramids that share corners with four equivalent Na(1)O6 octahedra, corners with four equivalent Cd(1)O6 pentagonal pyramids, corners with four equivalent P(1)O4 tetrahedra, edges with two equivalent Na(1)O6 octahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 63-78°. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Cd(1)O6 pentagonal pyramids, edges with two equivalent Na(1)O6 octahedra, and  an edgeedge with one Cd(1)O6 pentagonal pyramid. The corner-sharing octahedral tilt angles range from 56-58°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Cd(1), and one P(1) atom. In the second O site, O(2) is bonded to one Na(1), two equivalent Cd(1), and one P(1) atom to form distorted corner-sharing ONaCd2P trigonal pyramids. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Na(1), two equivalent Cd(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Cd(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
