1,10-Phenanthroline-5,6-dione (1.5 mmol) and 3-cyanobenzaldehyde (1.5 mmol) were dissolved in CH3COOH and CH3COONH4 (1:1) solution (30 ml). The mixture was refluxed for 1.5 h under argon, after cooling this mixture was diluted with water and neutralized with concentrated aqueous ammonia, immediately resulting a yellow precipitate, which was washed with water, acetone and diethyl ether respectively. Crystals of the title compound were obtained by recrystallization from dichloromethane-methanol solution.
Methanol H atom was located in a difference Fourier map and refined as riding in as-found relative position, the thermal parameter was refined. Other H atoms were placed in calculated positions with C—H = 0.93 Å (aromatic), 0.96 Å (methyl) and N—H = 0.86 Å, and refined using a riding model, with Uiso(H) = 1.5Ueq(C) for methyl H and 1.2Ueq(C,N) for the others.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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. |

1,10-Phenanthroline and its derivatives are commonly used as ligands in metal-organic coordination polymers (Sun et al., 2007; Yin, 2008; Zhang et al., 2008). The title compound was synthesized from 1,10-phenanthroline-5,6-dione.
The asymmetric unit of the title compound, C20H11N5.CH3OH, contains one organic molecule and one solvent methanol molecule (Fig.1). The molecules are connected by N—H···O and O—H···N hydrogen bonding to form a one-dimensional chain (Fig. 2). The organic molecule is essentially planar.
