RbZrCdF7 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent F(1), four equivalent F(2), and four equivalent F(3) atoms. Zr(1) is bonded to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form ZrF7 pentagonal bipyramids that share corners with three equivalent Cd(1)F7 pentagonal bipyramids and edges with two equivalent Cd(1)F7 pentagonal bipyramids. Cd(1) is bonded to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form CdF7 pentagonal bipyramids that share corners with three equivalent Zr(1)F7 pentagonal bipyramids and edges with two equivalent Zr(1)F7 pentagonal bipyramids. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to one Rb(1), one Zr(1), and one Cd(1) atom. In the second F site, F(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Zr(1), and one Cd(1) atom. In the third F site, F(3) is bonded to two equivalent Rb(1), one Zr(1), and one Cd(1) atom to form a mixture of distorted face and corner-sharing FRb2ZrCd tetrahedra. In the fourth F site, F(4) is bonded in a linear geometry to one Zr(1) and one Cd(1) atom.
