Source of material

The title compound was synthesized according to the literature procedures [1, 2] using 1,10-phenanthrolin-5-amine (0.359 g, 1.84 mmol) and 2-hydroxy-4-methylbenzaldehyde (0.254 g, 1.87 mmol) in methanol. The product was obtained as an orange powder which was washed with cold methanol and dried. Crystals suitable for X-ray diffraction were obtained from slow evaporation of an acetone solution. Yield: 0.587 g, 95%. 1H-NMR (401 MHz, CDCl3) δ = 12.77 (s, 1H, -OH), 9.09 (m, 2H), 8.69 (s, 1H, HC-N), 8.56 (dd, 1H, J = 8.3, 1.7 Hz), 8.13 (dd, 1H, J = 8.2, 1.7 Hz), 7.60 (d, 1H, J = 4.0 Hz), 7.53 (d, 1H, J = 8.1 Hz), 7.30 (s, 1H), 7.28 (s, 1H), 6.85 (s, 1H), 6.74 (s, 1H), 2.33 (s, 3H, CH3), 1.75 (s, 2H, H2O). 13C-NMR (100 MHz, CDCl3) δ = 164.6, 161.2, 150.8, 149.7, 146.3, 145.5, 145.3, 145.2, 135.8, 132.6, 132.0, 128.6, 125.3, 123.4, 123.2, 120.8, 117.7, 116.6, 112.4, 22.0.

Experimental details

In the structure all the H atoms were positioned geometrically and refined discernibly using a riding model, with C—Hmethine = 1.00 Å; C—Hmethyl = 0.98 Å; C—Haromatic = 0.95 Å. The hydrogen atoms of the methyl groups were generated to fit the difference electron density and the groups were then refined as rigid rotors. H atoms bonded to O1 and O2 atoms were placed according to the electron-density map.

Discussion

The development of coordination chemistry has seen the use of a few classic ligand systems whose diversity allows their use in multiple disciplines due to the ease of binding to several transition metals. One such system is the bidentate ligand, N,N-1,10-phenanthroline (Phen). Phen has found valuable application in a vast field of chemistry ranging from analytical, organic, inorganic and supramolecular chemistry [3–5]. It has several structural features which make it a favourable chelating ligand, such as its rigidity and planarity. The two nitrogen atoms are permanently placed in juxtaposition, ideal for bidentate binding to metal ions, without the possibility of free rotation seen in the 2,2′-dipyridyl ligand. It is hydrophobic and can behave as a π-acceptor chelator despite the poor σ-donor capability of the heteroaromatic nitrogen atoms [3]. Phen has further distinct chemical advantages, as its planarity allows phen complexes to intercalate with DNA and RNA via aromatic π-stacking [6]. In addition, the photochemical and photophysical properties of phen-based complexes has found application in catalysis, luminescent materials and bio-medical fields [7–9]. Our interest in bifunctional chelator systems for the use in radiopharmaceutical drug design, has led us to combine the advantageous characteristics of the 1,10-phenanthroline based ligands with the salicylidene Schiff base derivatives. The title compound contains the 1,10-phenanthroline derivative linked to a 2-hydroxybenzaldehyde supporting backbone. The title compound is an asymmetric Schiff-base which has crystallised in the phenol-imine tautomeric form [10, 11] with a co-crystallised water molecule. A strong intramolecular hydrogen bond occurs between the O1—H1A⋯N1 atoms, a common property for such systems. The compound is non-planar with a dihedral angle of 50.99(4)° between the two aromatic ring systems (plane 1 = C11 – C16 and plane 2 = C21 – C31, N2, N3). The C1—N1 bond distance of 1.291(1) Å is indicative of a double bond whereas the N1—C21 and O1—C12 bond distances (1.416(2) and 1.359(1) Å) are longer due to their single bond nature [12]. The compound shows staggered head-to-head packing along the c-axis, supported by intermolecular hydrogen bonding between the hyrogen atoms of the water molecule and the phenanthroline nitrogen atoms (N2, N3) of neighbouring molecules.
