The structure described by RbNaCd3O4 crystallizes in the monoclinic Cm space group. Rb(1) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Na(1) is bonded to one O(1), one O(4), and two equivalent O(3) atoms to form NaO4 trigonal pyramids that share corners with two equivalent Na(1)O4 trigonal pyramids, corners with three equivalent Cd(2)O4 trigonal pyramids, corners with three equivalent Cd(3)O4 trigonal pyramids, and edges with two equivalent Cd(1)O4 tetrahedra. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one O(2), one O(3), and two equivalent O(4) atoms to form CdO4 tetrahedra that share corners with two equivalent Cd(1)O4 tetrahedra, corners with three equivalent Cd(2)O4 trigonal pyramids, corners with three equivalent Cd(3)O4 trigonal pyramids, and edges with two equivalent Na(1)O4 trigonal pyramids. In the second Cd site, Cd(2) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form CdO4 trigonal pyramids that share corners with three equivalent Cd(1)O4 tetrahedra, corners with two equivalent Cd(2)O4 trigonal pyramids, corners with three equivalent Na(1)O4 trigonal pyramids, and edges with two equivalent Cd(3)O4 trigonal pyramids. In the third Cd site, Cd(3) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form CdO4 trigonal pyramids that share corners with three equivalent Cd(1)O4 tetrahedra, corners with two equivalent Cd(3)O4 trigonal pyramids, corners with three equivalent Na(1)O4 trigonal pyramids, and edges with two equivalent Cd(2)O4 trigonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), one Na(1), one Cd(2), and two equivalent Cd(3) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1), one Cd(1), one Cd(3), and two equivalent Cd(2) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Na(1), one Cd(1), and one Cd(2) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to two equivalent Rb(1), one Na(1), one Cd(3), and two equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
