RbNaS is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Rb(1) is bonded in a 5-coordinate geometry to five equivalent S(1) atoms. Na(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing NaS4 tetrahedra. S(1) is bonded in a 9-coordinate geometry to five equivalent Rb(1) and four equivalent Na(1) atoms.
RbNaS is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Rb(1) is bonded in a 5-coordinate geometry to five equivalent S(1) atoms. There is one shorter (3.37 Å) and four longer (3.50 Å) Rb(1)-S(1) bond lengths. Na(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing NaS4 tetrahedra. All Na(1)-S(1) bond lengths are 2.81 Å. S(1) is bonded in a 9-coordinate geometry to five equivalent Rb(1) and four equivalent Na(1) atoms.
