The title compound, C30H18ClNO, is a product of the condensation reaction of acenaphthylene-1,2-dione and 5′-chloro-1,1′:3′,1′′-terphenyl-4′-amine. The acenaphthylene fragment and two terminal phenyl rings are rotated relative to the central benzene ring by 72.2 (3), 43.2 (3) and 41.2 (3)°, respectively. This molecular conformation is supported by weak C—H⋯π interactions. In the crystal, molecules form centrosymmetric dimers by the stacking interactions between two neighboring acenaphthylene fragments, with an interplanar distance of 3.365 (3) Å. The dimers are bound to each other by weak C—H⋯N and C—H⋯π interactions, forming a three-dimensional framework.

Formic acid (1 mL) was added to a stirred solution of acenaphthenequinone (1.2 mmol) and 2-chloro-4,6-diphenylaniline (1.2 mmol) in methanol (20 mL). The mixture was refluxed for 24 h, then cooled, and the precipitate was separated by filtration. The solid was recrystallized from dichloromethane/cyclohexane (v/v = 8:1), washed with cold ethanol and dried under vacuum to give the title compound I. Yield is 0.15 g (83%). Crystals of I suitable for X-ray
were grown from a cyclohexane/dichloromethane (1:2, v/v) solution. Anal. Calcd. for C30H18ClNO: C, 81.17; H, 4.09; N,3.16. Found: C, 81.11; H, 4.19; N, 3.12.All hydrogen atoms were placed in the calculated positions with C—H = 0.93 Å and refined in the riding model with fixed isotropic displacement parameters [Uiso(H) = 1.2Ueq(C)].
Schiff bases often exhibit various biological activities, for example, anti-inflammatory, antibacterial, anticancer and antitoxic properties (Lozier et al., 1975). They have also been used as versatile ligands in coordination chemistry (Kargar et al., 2009; Yeap et al., 2009). The present work describes the structure of a new Schiff base, C30H18ClNO, (I) obtained by the condensation reaction of acenaphthylene-1,2-dione and 5'-chloro-1,1':3',1''-terphenyl-4'-amine (Figure 1).
The geometrical parameters of I are in good accordance with those found in the related compounds (Higuchi et al., 2001; Manseong et al., 2006; Vitor et al., 2008). The acenaphthylene fragment and two terminal phenyl rings in I are rotated in relative to the central benzene ring by 72.2 (3), 43.2 (3) and 41.2 (3)°, respectively (Figure 2). The π(C13=C14) [H2···C13 2.76 Å, H2···C14 2.80 Å] hydrogen bonding interactions (Figure 2).
of I is supported by the weak intramolecular C20—H20···N2 (Table 1) and C2—H2···In the crystal, the molecules form centrosymmetric dimers by the stacking interactions between two neighboring acenaphthylene fragments, with the interplane distance of 3.365 (3) Å. The dimers are bound to each other by the weak C24—H24···N2i, C4—H4···Cg1ii (Cg1 is the centroid of the C25/C26/C27/C28/C29/C30 ring) and C6—H6···Cg2iii (Cg2 is the centroid of the C19/C20/C21/C22/C23/C24 ring) hydrogen bonding interactions (Table 1) into 3-dimensional framework. Symmetry codes: (i) –x+1/2, y+1/2, –z+1/2; (ii) x–1/2, –y+1/2, z–1/2; (iii) –x+1, –y+1, –z+1.

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. |

Schiff bases often exhibit various biological activities, for example, anti-inflammatory, antibacterial, anticancer and antitoxic properties (Lozier et al., 1975). They have also been used as versatile ligands in coordination chemistry (Kargar et al., 2009; Yeap et al., 2009). The present work describes the structure of a new Schiff base, C30H18ClNO, (I) obtained by the condensation reaction of acenaphthylene-1,2-dione and 5'-chloro-1,1':3',1''-terphenyl-4'-amine (Figure 1).
The geometrical parameters of I are in good accordance with those found in the related compounds (Higuchi et al., 2001; Manseong et al., 2006; Vitor et al., 2008). The acenaphthylene fragment and two terminal phenyl rings in I are rotated in relative to the central benzene ring by 72.2 (3), 43.2 (3) and 41.2 (3)°, respectively (Figure 2). The molecular conformation of I is supported by the weak intramolecular C20—H20···N2 (Table 1) and C2—H2···π(C13=C14) [H2···C13 2.76 Å, H2···C14 2.80 Å] hydrogen bonding interactions (Figure 2).
In the crystal, the molecules form centrosymmetric dimers by the stacking interactions between two neighboring acenaphthylene fragments, with the interplane distance of 3.365 (3) Å. The dimers are bound to each other by the weak C24—H24···N2i, C4—H4···Cg1ii (Cg1 is the centroid of the C25/C26/C27/C28/C29/C30 ring) and C6—H6···Cg2iii (Cg2 is the centroid of the C19/C20/C21/C22/C23/C24 ring) hydrogen bonding interactions (Table 1) into 3-dimensional framework. Symmetry codes: (i) –x+1/2, y+1/2, –z+1/2; (ii) x–1/2, –y+1/2, z–1/2; (iii) –x+1, –y+1, –z+1.
