The 25H22NO2+·Br −·0.5CH2Cl2·0.5H2O, comprises two pseudosymmetry-related cations, two bromide anions, a dichloromethane molecule and a water molecule of solvation. The two independent cations are conformationally similar with the comparative dihedral angles between the central pyridine ring and the three benzene substituent rings being 3.0 (2), 36.4 (1) and 24.2 (1)°, and 3.7 (2), 36.5 (1) and 24.8 (1)°, respectively. In the crystal, the cations, anions and water molecules are linked through O—H⋯O and O—H⋯Br hydrogen bonds, forming an insular unit. Within the cations there are also intramolecular N—H⋯O hydrogen bonds. Adjacent centrosymmetrically related aggregates are linked by π–π stacking interactions between the pyridine ring and a benzene ring in both cations [ring-centroid separations = 3.525 (3) and 3.668 (3) Å], forming chains extending across the ac diagonal. Voids between these chains are filled by dichloromethane molecules.

The precursor of the title salt, 2,6-bis(2'-hydroxy-5'-methylphenyl)-4- phenylpyridine, was obtained from 2-hydroxy-5-methylacetophenone via two parallel reactions: (a), condensation of the above acetophenone with benzaldehyde in the presence of NaOH and (b), iodination of above acetophenone in the presence of pyridine. The reaction of an equimolar mixture of the above intermediates with ammonium acetate led to formation of the precursor, with moderate yield.

Crystals of the title compound suitable for X-ray analysis were precipitated from the reaction of 2,6-bis(2'-hydroxy-5'-methylphenyl)-4-phenylpyridine with silicon tetrabromide in dichloromethane.
All hydrogen atoms on aromatic atoms (both C and N) and methyl groups were placed in calculated positions and refined using a riding model, with C—H = 0.95–0.98 Å, with N—H = 0.88 Å, and with Uiso(H) = 1.2 Ueq(C,N) or 1.5 Ueq(C) for methyl H atoms. A rotating model was applied to the methyl groups. All hydroxy and water hydrogen atoms were found from difference Fourier syntheses and refined with Uiso(H) = 1.5 Ueq(O) and restrained O—H distances (SADI). Three outliers (-1 1 1, 0 1 1, 1 1 0) were omitted from the data set in the last cycles of refinement.
Interest in dianionic tridentate ONO-type ligands has grown steadily over the past several decades due to their ability to stabilize unusual metal oxidation states and the coordination geometry around metal centers. As a part of our investigation on the synthesis of tridentate ligands (Kireenko et al., 2013; Huang et al., 2013, 2012) we obtained and studied the structure of the title compound, 2(C25H22NO2+) . 2Br - . CH2Cl2 . H2O, which may be regarded as a precursor of a promising ligand for the preparation of complexes of main group metal elements.
The
comprises two independent ligand cations, two bromide anions, a dichlormethane and a water molecule of solvation (Fig. 1). The cations are related by pseudotranslation (one half of the ab diagonal) and possess very similar geometrical parameters and conformations. The comparative dihedral angles between the central pyridine ring and the three benzene substituent rings are 3.0 (2), 36.4 (1), 24.2 (1)° and 3.7 (2), 36.5 (1), 24.8 (1)°, respectively for cations 1 and 2. Figure 2 represents the superposition of one independent cation with another shifted by x + 0.5, y + 0.5, z. However, the bromide anions and the solvent water molecules do not satisfy this law.In the crystal, the two crystallographically independent organic cations, the two bromide anions, and the water molecules are associated through moderately strong inter-species O—H···O and O—H···Br hydrogen bonds (Table 1), forming an insular framework (Fig. 3). Within the unit there are also intramolecular N—H···O hydrogen bonds. Adjacent centrosymmetrically- related aggregates are linked by π–π stacking interactions between the pyridine ring (N1–C31 in cation 1 and N2–C61 in cation 2) and a benzene ring (C11–C16 in cation 1 and C41–C46 in cation 2), giving ring centroid separations of 3.525 (3) and 3.668 (3) Å, respectively. This results in the formation of chains extending across the ac diagonal (Fig. 4).

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. |

Interest in dianionic tridentate ONO-type ligands has grown steadily over the past several decades due to their ability to stabilize unusual metal oxidation states and the coordination geometry around metal centers. As a part of our investigation on the synthesis of tridentate ligands (Kireenko et al., 2013; Huang et al., 2013, 2012) we obtained and studied the structure of the title compound, 2(C25H22NO2+) . 2Br - . CH2Cl2 . H2O, which may be regarded as a precursor of a promising ligand for the preparation of complexes of main group metal elements.
The asymmetric unit comprises two independent ligand cations, two bromide anions, a dichlormethane and a water molecule of solvation (Fig. 1). The cations are related by pseudotranslation (one half of the ab diagonal) and possess very similar geometrical parameters and conformations. The comparative dihedral angles between the central pyridine ring and the three benzene substituent rings are 3.0 (2), 36.4 (1), 24.2 (1)° and 3.7 (2), 36.5 (1), 24.8 (1)°, respectively for cations 1 and 2. Figure 2 represents the superposition of one independent cation with another shifted by x + 0.5, y + 0.5, z. However, the bromide anions and the solvent water molecules do not satisfy this pseudosymmetry law.
In the crystal, the two crystallographically independent organic cations, the two bromide anions, and the water molecules are associated through moderately strong inter-species O—H···O and O—H···Br hydrogen bonds (Table 1), forming an insular framework (Fig. 3). Within the unit there are also intramolecular N—H···O hydrogen bonds. Adjacent centrosymmetrically- related aggregates are linked by π–π stacking interactions between the pyridine ring (N1–C31 in cation 1 and N2–C61 in cation 2) and a benzene ring (C11–C16 in cation 1 and C41–C46 in cation 2), giving ring centroid separations of 3.525 (3) and 3.668 (3) Å, respectively. This results in the formation of chains extending across the ac diagonal (Fig. 4).
