The title compound, C28H21N3S, crystallizes with two molecules in the asymmetric unit. There are only very slight differences in the torsion angles between the two molecules. The two molecules are stabilized by intramolecular N-H
N interactions and the crystal packing is stabilized by intermolecular N-H
S interactions.
The compound 1-(2-((anthracene-10-yl)methyleneamino)phenyl)-3-phenylthiourea was synthesized by Schiff base condensation between1-(2-aminophenyl)-3-phenyl thiourea and 9-anthraldehyde. To the solution of 1-(2-aminophenyl)-3-phenyl thiourea (0.5 g, 2.05 mmol) in methanol (25 ml), 4-nitrobenzaldehyde (0.424 g, 2.05 mmol) in methanol was added under stirring. The resulting mixture was heated at reflux for 3 h and cooled to room temperature. The solid product was collected by filtration and washed with cold methanol. The microcrystalline compound was recrystallized from hot acetonitrile; yellow coloured crystals suitable for X ray diffraction were obtained on slow evaporation [yield 82.9%,; m.p.: 453 K]
All H-atoms were refined using a riding model with C—H = 0.93Å and N—H = 0.86 Å with Uiso(H)=1.2Ueq (C,N).

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. |

The design and synthesis of anion receptors possessing high affinity and selectivity represents a challenge that continues to attract considerable attention within the molecular recognition and supramolecular chemistry communities due to the important role anions play in areas as diverse as the environment and medicine (Lee et al., 2005). Of particular interest in this regard are colorimetric anion sensors and fluoresecent chemosensors for anions. Recent efforts to investigate anion binding by naked eye detection (Lee et al., 2003) and through flouresencent changes (Yoon et al., 2004) may provide important results. The most desirable property of an anion sensor based on fluoresecence is the ability to respond to applied perturbation in a highly selective and sensitive manner by dramatic change in emission colour and/or intensity.
The title compound crystallizes in triclinic system with two molecules in asymmetric unit. The bond lengths, bond angles and torsion angles of the title compound are comparable with the similar structure solved earlier (Gayathri et al., 2007). The dihedral angle between the phenyl rings C1–C6 and C8–C13 in molecule A and between C29–C34 and C36–C41 in molecule B are 18.3 (1) and 20.0 (1)°, respectively. The acenapthene moiety in both the molecules are planar as analysed based on the dihedral angles between the rings in the acenapthene moiety.
The two molecules are stabilized by N—H···N intramolecular interactions generating S(5) motif. The crystal packing is stabilized by N—H···S intermolecular interactions generating centrosymmetric dimer of R22(8) ring.
