The 16H20N2O2, consists of two independent molecules differing slightly in the conformations of the seven-membered rings and the butyl substituents, where the benzene rings are oriented at a dihedral angle of 34.56 (3)°. In the crystal, pairwise intermolecular C—H⋯O and complementary intramolecular C—H⋯O hydrogen bonds form twisted strips extending parallel to (012). These strips are connected into layers parallel to (111) by additional intermolecular C—H⋯O hydrogen bonds. The layers are further joined by C—H⋯π interactions. The Hirshfeld surface analysis of the indicates that the most important contributions for the crystal packing are from H⋯H (65.5%), H⋯C/C⋯H (16.0%) and H⋯O/O⋯H (15.8%) interactions.

1. Chemical context
1,5-Benzodiazepine derivatives constituted an important class of et al., 1991), hypnotic (Kudo et al., 1982), anti-HIV-1 (Di Braccio et al., 2001), anticonvulsant (De Sarro et al., 1996), antimicrobial (Kumar et al., 2007) and antitumor (Kamal et al., 2008) activities. The present work is a continuation of the synthesis of the N-substituted 1,5-benzodiazepines derivatives performed recently by our team (Sebhaoui et al., 2016, 2017; Chkirate et al., 2018). In this work, we prepared the title compound, for an investigation of its biological activities, by reacting (Z)-4-(2-oxopropylidene)-4,5-dihydro-1H-benzo[b][1,5]diazepin-2(3H)-one with 1-bromobutane, under liquid–liquid (PTC) conditions using tetra n-butyl ammonium bromide (TBAB) as catalyst and an aqueous solution of potassium hydroxide as base in dichloromethane (Fig. 1). We report herein its crystal and molecular structures along with the Hirshfeld surface analysis.
possessing a wide spectrum of biological properties. They exhibit anti-inflammatory (Roma2. Structural commentary
The B (N1/N2/C1/C6–C9) and D (N3/N4/C17/C22–C25) rings and the n-butyl substituents, where the benzene A (C1–C6) and C (C17–C22) rings are oriented at a dihedral angle of 34.56 (3)°. Rings B and D have boat conformations with slightly different Cremer–Pople puckering parameters [for ring B: Q(2) = 0.8872 (13) Å, Q(3) = 0.2030 (13) Å, φ(2) = 28.49 (8)° and φ(3) = 138.6 (4)°, QT = 0.9102 (13) Å and for ring D: Q(2) = 0.8631 (13) Å, Q(3) = 0.2113 (13) Å, φ(2) = 24.61 (8)° and φ(3) = 136.8 (3)°, QT = 0.8886 (13) Å]. In the n-butyl substituents, the C13—C14—C15—C16 [177.96 (13)°] and C29—C30—C31—C32 [174.97 (12)°] chains also have slightly different torsion angles. The conformation of the 2-oxopropylidene units are partially determined by the intramolecular N—H⋯O hydrogen bonds (Table 1, Fig. 1) The r.m.s. deviation of the overlay of two molecules is 0.1367 Å.
of the title compound consists of two independent molecules differing modestly in the conformations of the seven-membered3. Supramolecular features
Hydrogen bonding and van der Waals contacts are the dominant interactions in the crystal packing. In the crystal, pairwise intermolecular C—HBnz⋯OOxoprp (Bnz = Benzene and Oxoprp = 2-oxopropylidene) and complementary intramolecular C—HBnz⋯OBnzdzp (Bnzdzp = 1,5-benzodiazepin-2-one) hydrogen bonds (Table 1) form twisted strips extending parallel to (012) (Fig. 2). These strips are connected into layers parallel to (111) (Fig. 3) by intermolecular C—HBnz⋯OOxoprp and C—HBnzdzp⋯OBnzdzp hydrogen bonds (Table 1). The layers are further joined by C—HBnzdzp⋯π and C—HBty⋯π (Bty = n-butyl) interactions (Table 1 and Figs. 2 and 3).
4. Hirshfeld surface analysis
In order to visualize the intermolecular interactions in the crystal of the title compound, a Hirshfeld surface (HS) analysis (Hirshfeld, 1977; Spackman & Jayatilaka, 2009) was carried out by using Crystal Explorer17.5 (Turner et al., 2017). In the HS plotted over dnorm (Fig. 4), the white surface indicates contacts with distances equal to the sum of van der Waals radii, and the red and blue colours indicate distances shorter (in close contact) or longer (distinct contact) than the van der Waals radii, respectively (Venkatesan et al., 2016). The bright-red spots appearing near O1, O2, O3 and hydrogen atoms H18, H19 and H28C indicate their roles as the respective donors and acceptors in the dominant C—H⋯O and N—H⋯O hydrogen bonds. The shape-index of the HS is a tool for visualizing π–π stacking interactions by the presence of adjacent red and blue triangles; if there are no adjacent red and/or blue triangles, then there are no π–π interactions. Fig. 5 clearly suggests that there are no π–π interactions.
The overall two-dimensional fingerprint plot, Fig. 6a, and those delineated into H⋯H, H⋯C/C⋯H, H⋯O/O⋯H, H⋯N/N⋯H, O⋯C/C⋯O, N⋯C/C⋯N and C⋯C contacts (McKinnon et al., 2007) are illustrated in Fig. 6b–h, respectively, together with their relative contributions to the Hirshfeld surface. The most important interaction is H⋯H contributing 65.5% to the overall crystal packing, which is reflected in Fig. 6b as widely scattered points of high density due to the large hydrogen-atom content of the molecule. The wide peak in the centre at de = di = 1.16 Å in Fig. 6b is due to the short interatomic H⋯H contacts (Table 2). In the presence of weak C—H⋯π interactions (Table 1) in the crystal, the pair of characteristic wings resulting in the fingerprint plot delineated into H⋯C/C⋯H contacts, Fig. 6c, the 16.0% contribution to the HS is viewed as pair of spikes with the tips at de + di ∼ 2.73 Å. The H⋯O/O⋯H contacts in the structure, with 15.8% contribution to the HS, have a symmetrical distribution of points, Fig. 6d, with the tips at de + di ∼2.24 Å arising from the short intra- and/or interatomic C—H⋯O and N—H⋯O hydrogen bonding (Table 1) as well as from the H⋯O/O⋯H contacts (Table 2). Finally, the H⋯N/N⋯H (Fig. 6e) contacts (Table 2) in the structure, with a 1.4% contribution to the HS, have a symmetrical distribution of points, with a pair of wings appearing at de = di = 2.67 Å. The Hirshfeld surface representations for dnorm are shown for the H⋯H, H⋯C/C⋯H and H⋯O/O⋯H interactions in Fig. 7a–c, respectively.

The Hirshfeld surface analysis confirms the importance of H-atom contacts in establishing the packing. The large number of H⋯H, H⋯C/C⋯H and H⋯O/O⋯H interactions suggest that van der Waals interactions and hydrogen bonding play the major roles in the crystal packing (Hathwar et al., 2015).
5. Synthesis and crystallization
To a solution of (Z)-4-(2-oxopropylidene)-4,5-dihydro-1H-benzo[b][1,5]diazepin-2(3H)-one (2.38 mmol) in 15 ml of dichloromethane were added 1.5 eq of 1-bromobutane, (3.57 mmol) of potassium hydroxide dissolved in water and 0.23 mmol of tetra-n-butyl ammonium bromide (BTBA). The mixture was kept under magnetic stirring at room temperature for 48 h. A little water was added and then the organic phase was extracted. The mixture obtained was chromatographed on a column of silica gel (eluent hexane/ethyl acetate 8/2) to give three products. The title compound was isolated as the major product in a yield of 77%.
6. Refinement
Crystal data, data collection and structure . H atoms attached to C28 did not give a satisfactory geometry so they were positioned geometrically with C—H = 0.98 Å, and refined as riding with Uiso(H) = 1.5Ueq(C). The remaining H atoms were located in a difference-Fourier map and were freely refined. The crystal studied was twinned.

Experimental. The diffraction data were obtained from 3 sets of 400 frames, each of width 0.5° in ω, colllected at φ = 0.00, 90.00 and 180.00° and 2 sets of 800 frames, each of width 0.45° in φ, collected at ω = –30.00 and 210.00°. The scan time was 20 sec/frame. Analysis of 641 reflections having I/σ(I) > 13 and chosen from the full data set with CELL_NOW (Sheldrick, 2008) showed the crystal to belong to the triclinic system and to be twinned by a 180° rotation about the reciprocal axis [111]. The raw data were processed using the multi-component version of SAINT under control of the two-component orientation file generated by CELL_NOW. |
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. Refined as a 2-component twin. Individual refinement of the H-atoms attached to C28 did not give a satisfactory geometry so these were included as riding contributions in idealized positions. |
