The crystal structure described by NaCdAlF6 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded to one F(2), one F(4), two equivalent F(3), and two equivalent F(5) atoms to form distorted NaF6 octahedra that share corners with two equivalent Cd(1)F7 hexagonal pyramids, corners with five equivalent Al(1)F6 octahedra, edges with two equivalent Cd(1)F7 hexagonal pyramids, and edges with two equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 53-55°. Cd(1) is bonded to one F(4), one F(5), two equivalent F(1), and three equivalent F(2) atoms to form distorted CdF7 hexagonal pyramids that share corners with two equivalent Na(1)F6 octahedra, corners with two equivalent Al(1)F6 octahedra, edges with four equivalent Cd(1)F7 hexagonal pyramids,  an edgeedge with one Al(1)F6 octahedra, and edges with two equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 51-53°. Al(1) is bonded to one F(1), one F(3), one F(4), one F(5), and two equivalent F(6) atoms to form AlF6 octahedra that share corners with two equivalent Cd(1)F7 hexagonal pyramids, corners with two equivalent Al(1)F6 octahedra, corners with five equivalent Na(1)F6 octahedra, and  an edgeedge with one Cd(1)F7 hexagonal pyramid. The corner-sharing octahedral tilt angles range from 4-55°. There are six inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Cd(1) and one Al(1) atom.

In the third F site, F(3) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one Al(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Na(1), one Cd(1), and one Al(1) atom. In the fifth F site, F(5) is bonded to two equivalent Na(1), one Cd(1), and one Al(1) atom to form distorted FNa2AlCd tetrahedra that share  a cornercorner with one F(2)NaCd3 tetrahedra, corners with two equivalent F(5)Na2AlCd tetrahedra, and edges with two equivalent F(2)NaCd3 tetrahedra.
