Abstract

The title compound, C12H9N2O2 +·Cl·2H2O, exhibits a layered structure which is stabilized by inter­molecular O—H(...)O, O—H(...)Cl and N+—H(...)Cl hydrogen bonds, and π–π inter­actions (centroid–centroid distances = 3.654 and 3.583 Å). The distances between the molecules are 3.371 and 3.294 Å.

Comment

The title compound, [C12H9N2O2]Cl.2H2O, was obtained unintentionally as the product of an attempted synthesis of a condensation product between 1,10-phenanthroline-5,6-dione and picoloylhydrazide. Compared with a similar compound (5,6-dioxo-1,10-phenanthrolin-1-ium chloride) reported (Borel & Bond, 2008), the Cl—H distance is slightly longer (2.372 vs 2.274Å).

The structure of the title compound is shown in Fig. 1. It exhibits a layered structure which is stabilized by inter-molecular O—H···O, O—H···Cl-, N+—H···Cl- hydrogen bonds, detailed in Fig. 2 and Table 1, as well as π-π interactions and C—H···O, C—H···Cl- interactions. With Cl- as the connecting point, it occurs two different shape parallelograms made up of O and Cl-. The dihedral angle between the two planes, which possess different shapes, is 78.67°. The distances between the layers, which belong to offset face to face, are 3.371 Å and 3.294 Å, reflecting π-π interactions.

Experimental

1,10-phenanthroline-5,6-dione (300 mg, 1.53 mmol) was dissolved in a mixed solution of 10 ml CH2Cl2 and 30 ml EtOH when heating with stirring. When all of the compound dissolved, picoloylhydrazide (200 mg, 1.46 mmol) was added and refluxed 8hrs. Then HCl(aq) was added until the pH was 6. Red crystals of the title compound were obtained by slow evaporation of solvent at room temperature. Analysis: Found C 50.45, H 4.82, N 9.71%, calc. for C12H13ClN2O4, C 50.63, H 4.60, N 9.84%.

Refinement

The positions of the O1- , O2- and N2-bound H atoms were placed at fixed positions and refined accord to the riding model. O3- and O4-bound H atoms were located in a difference Fourier map and refined freely. The C-bound H atoms were included in the riding model approximation with C—H = 0.93 Å and Uiso of each H atom = 1.2Ueq(C).

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
