Bis(2,9-dimethyl-1,10-phenanthrolin-1-ium) hydrogen (S,S)-tartrate nonahydrate

Z. Derikvand and M. M. Olmstead

Abstract: The asymmetric unit of the title compound, 2C₁₄H₁₃N₂⁺·2C₄H₅O₆^-·9H₂O, contains two cations and two anions in addition to nine molecules of water. Each of the hydrogen tartrate anions is hydrogen bonded to itself by translation along [100] in a head-to-tail fashion via a short hydrogen bond with donor-acceptor distances of 2.473 (4) and 2.496 (4) Å. A large number of intermolecular O-HO, N-HO and C-HO hydrogen-bonding interactions, as well as - stacking [centroid-centroid distances in the range 3.642 (3) to 3.866 (3) Å], play an important role in the crystal structure.
