The title compound, C32H21N4·C2H5OH, crystallized as an ethanol monosolvate. In the molecule of this phenanthroline derivative, the pyridine rings are almost coplanar, making a dihedral angle of 1.54 (13)°. The triphenylamine group, introduced as an shows a propeller-type structure, and the dihedral angles between the benzene rings are 68.71 11), 63.92 (16) and 70.81 (15)°. In the crystal, the phenanthroline molecules are linked via the solvent molecule by N—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds, leading to the formation of zigzag chains propagating along [010]. These chains are linked via C—H⋯N hydrogen bonds, forming undulating two-dimensional networks extending in the a- and b-axis directions.

A mixture of 4-formyl triphenylamine (0.19 g, 0.7 mmol), 1,10-phenanthroline-5,6-dione (0.15 g, 0.7 mmol), ammonium acetate (1.15 g, 15 mmol) and 15 mL acetic acid were heated and refluxed for 4 h, then cooled to room temperature. 30 mL water was added and a saturated K2CO3 solution was added slowly to adjust the pH to 7–8. A yellow precipitate was generated gradually, suction filtered and washed with water three times, and recrystallized from ethanol to give a pale-yellow bock-like crystals (0.28 g; Yield 85%) Spectroscopic details for the title compound are available in the archived CIF.
The amine H atoms were located in a difference Fourier map and freely refined. The OH and C-bound H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms: O—H = 0.82 Å, C—H = 0.93–0.97 Å, with Uiso(H) = 1.5Ueq(atoms C33 and O1), and = 1.2Ueq(C) for other H atoms.
1H-imidazo [4.5 - f] [1,10] phenanthroline derivatives have good biocompatibility and coordination ability (Li et al., 2012). Such compounds are often used to coordinate with various metal ions, and their binding with DNA to achieve anti-cancer anti-tumor activity has been studied (Ma et al., 2009; Xu et al., 2012 ; Zheng et al., 2013). The crystal structures of similar compounds have been reported (Sun et al., 2009; Eseola et al., 2012; Bhat et al., 2011). As a part of ongoing study of this type compound, here we report on the
of the title compound.The molecular structure of the title compound is illustrated in Fig. 1. It is comprised of a phenanthroline derivative and an ethanol solvent molecule (Fig. 1 and Table 1). The triphenylamine group, introduced as an
shows the propeller structure, with the dihedral angles between the benzene rings, (C15-C20), (C21-C26) and (C27-C32), being 68.71 (11), 63.92 (16) and 70.81 (15) °, respectively.The two pyridine rings of the phenanthroline group are almost coplanar, with a dihedral angle of 1.54 (13)°. The mean plane of imidazo-phenanthroline group (N1-N3/C1-C14; r.m.s. 0.002) is inclined to the benzene ring to which it is attached by 7.63 (9)°.
In the crystal, the phenanthroline molecules are linked via the solvent molecule by N-H···O, O-H···N and C-H···O hydrogen bonds leading to the formation of zigzag chains propagating along [010]. These chains are linked via C-H···N hydrogen bonds forming undulating two-dimensional networks extending in the a and b directions (Fig. 2 and Table 1).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
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. |

1H-imidazo [4.5 - f] [1,10] phenanthroline derivatives have good biocompatibility and coordination ability (Li et al., 2012). Such compounds are often used to coordinate with various metal ions, and their binding with DNA to achieve anti-cancer anti-tumor activity has been studied (Ma et al., 2009; Xu et al., 2012 ; Zheng et al., 2013). The crystal structures of similar compounds have been reported (Sun et al., 2009; Eseola et al., 2012; Bhat et al., 2011). As a part of ongoing study of this type compound, here we report on the crystal structure of the title compound.
The molecular structure of the title compound is illustrated in Fig. 1. It is comprised of a phenanthroline derivative and an ethanol solvent molecule (Fig. 1 and Table 1). The triphenylamine group, introduced as an electron donor, shows the propeller structure, with the dihedral angles between the benzene rings, (C15-C20), (C21-C26) and (C27-C32), being 68.71 (11), 63.92 (16) and 70.81 (15) °, respectively.
The two pyridine rings of the phenanthroline group are almost coplanar, with a dihedral angle of 1.54 (13)°. The mean plane of imidazo-phenanthroline group (N1-N3/C1-C14; r.m.s. 0.002) is inclined to the benzene ring to which it is attached by 7.63 (9)°.
In the crystal, the phenanthroline molecules are linked via the solvent molecule by N-H···O, O-H···N and C-H···O hydrogen bonds leading to the formation of zigzag chains propagating along [010]. These chains are linked via C-H···N hydrogen bonds forming undulating two-dimensional networks extending in the a and b directions (Fig. 2 and Table 1).
