Abstract

1,2-Benzothiazol-3(2H)-one 1,1 dioxide (more commonly known under its commercial name saccharin) forms a double salt with sodium and rubidium, Na+·Rb+·2C7H4NO3S·4H2O. The coordination numbers of the sodium and rubidium ions are 6 and 8, respectively; the coordination polyhedra can be described as distorted triangular and rectangular prisms. Both Rb+ and Na+ cations and flat saccharinate moieties are positioned at mirror planes parallel to the (010) crystallographic plane. Metal ions and saccharinate anions are assembled into infinite layers parallel to the (001) plane via electrostatic interactions and hydrogen-bonded networks. These layers are connected by stacking interactions and C—H...O hydrogen bonds into a three-dimensional structure.
