In the title hydrated molecular salt, C12H9N2+·C4H5O6·2H2O, the cation is almost planar (r.m.s. deviation = 0.014 Å); the carbon skeleton of the anion assumes a trans conformation [C—C—C—C torsion angle = −179.86 (14)°]. The carboxyl end of one hydrogen tartrate anion forms a short hydrogen bond to the carboxyl­ate end of another anion [O...O = 2.508 (2) Å] in a head-to-tail manner, forming a chain; the chains and water mol­ecules inter­act, generating an O—H...O hydrogen-bonded layer. The cation binds to the layer by an N—H...O hydrogen bond.

Comment top

D-tartaric acid transfers one proton to 1,10-phenanthroline to yield 1,10-phenanthroline hydrogen D-tartrate, which separates from solution as a trihydrate. The hydrogen D-tartrate anions are connected in a head-to-tail fashion by an O–Hcarboxylic acid···Ocarboxyl hydrogen bond [O···O 2.455 (1) Å] (Derikvand & Olmstead, 2010). The identical feature should be presented in the L analog (Wang et al., 2006). The anion and water molecules are linked by extensive O–H···O hydrogen bonds into a three-dimensional network, with the cations occupying the cavities. Racemic tartaric furnishes the corresponding dihydrate. In C12H9N2+ C4H5O4-.2H2O (Scheme I, Fig. 1), the carboxylic acid –CO2H end of one hydrogen (D,L)-tartrate anion forms a short hydrogen bond to the carboxylate –CO2- end of another anion [O···O 2.508 (2) Å] in a head-to-tail manner to form a chain; the chains and water molecules interact to generate an O–H···O hydrogen-bonded layer. The cation binds to the layer by an N–H···O hydrogen bond (Table 1).

Experimental top

D,L-Tartaric acid (2 mmol, 0.30 g) and 1,10-phenanthroline (0.33 mmol, 0.06 g) were dissolved in water (5 ml). The solution was heated briefly to dissolve the reactants. The solution was set aside for the growth of colorless crystals, which were isolated after 10 days. The bulk crystals were faintly tinted a shade of pink.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 to 1.00 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 U(C).

The ammonium and water H-atoms were located in a difference Fourier map, and were freely refined.

Omitted from the refinement owing to bad disagreements were these reflections: (-2 - 3 1), (-8 8 2), (2 2 4), (-7 6 7) and (3 - 3 4).
