Sodium dirubidium citrate, NaRb₂C₆H₅O₇, and sodium dirubidium citrate dihydrate, NaRb₂C₆H₅O₇(H₂O)₂.

ABSTRACT: The crystal structures of sodium dirubidium citrate {poly[μ-citrato-dirubi-dium(I)sodium(I)], [NaRb₂(C₆H₅O₇)] _n } and sodium dirubidium citrate dihydrate {poly[di-aqua-(μ-citrato)dirubidium(I)sodium(I)], [NaRb₂(C₆H₅O₇)(H₂O)₂] _n } have been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional techniques. Both structures contain Na chains and Rb layers, which link to form different three-dimensional frameworks. In each structure, the citrate triply chelates to the Na⁺ cation. Each citrate also chelates to Rb⁺ cations. In the dihydrate structure, the water mol-ecules are bond
