Abstract

The title compound, C15H13ClN4, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit, which are far from planar as a result of steric repulsion between the rings. The n class="Chemical">benzene and phenyl rings are inclined to the central pyrazole ring by 46.64 (10) and 17.87 (10)° in mol-ecule A, and by 40.02 (10) and 14.18 (10)° in mol-ecule B. The aromatic rings are inclined to one another by 58.77 (9)° in mol-ecule A, and 36.95 (8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked by two pairs of N-H⋯N hydrogen bonds forming A-B dimers. These are further linked by a fifth N-H⋯N hydrogen bond, forming tetra-mer-like units that stack along the a-axis direction, forming columns, which are in turn linked by C-H⋯π inter-actions, forming layers parallel to the ac plane.

Chemical context

The synthesis and reactions of benzodiazepin-2-ones and thio­nes have been studied in detail by our group (Gaponov et al., 2016 ▸; Okovytyy et al., 2009 ▸). The mechanism of n class="Chemical">ethanol-assisted hydrazinolysis of 1,3-di­hydro-2H-benzo[b][1,4]diazepine-2-thio­nes (Fig. 1 ▸) has been modelled by quantum-chemical calculations (Okovytyy et al., 2009 ▸). However, instead of obtaining the previously suggested products (IIIa) and (IIIb), compounds N 1-(5-phenyl-1H-pyrazol-3-yl)benzene-1,2-di­amine (Ia) and its 5-chloro-derivative (Ib) were prepared from 4-phenyl-1,3-di­hydro-2H-benzo[b][1,4]diazepine-2-thio­nes (IIa) and (IIb) and hydrazine hydrate (Fig. 1 ▸). Amino­pirazoles are useful building blocks for the synthesis of new pharmaceutical agents (Sakya et al., 2006 ▸) and agrochemicals (Yuan et al., 2013 ▸), due to their notable biological properties (Peng et al., 2013 ▸; Zhang et al., 2014 ▸; Ansari et al., 2017 ▸). The crystal structure analysis of the title compound, (Ib), was undertaken as it may help to provide a better understanding of the properties of amino­pirazoles.

Structural commentary

There are two independent mol­ecules (A and B) in the asymmetric unit of the title compound (Ib), as illustrated in Fig. 2 ▸. They are composed of three unsaturated rings, two of which are connected by a bridging amino group. The mol­ecules are not planar as a result of steric repulsion between the rings, which results in some disturbance of the conjugation. Thus, the presence of a shortened intra­molecular contact C2 ⋯ H11 [2.80 Å in mol­ecule A and 2.81 Å in mol­ecule B as compared with the sum of their van der Waals radii of 2.87 Å (Zefirov, 1997 ▸)], indicates the presence of repulsion between the n class="Chemical">pyrazole ring and the phenyl substituent. The steric strain is compensated for by the elongation of the C1—C10 bond: 1.486 (2) Å in mol­ecule A and 1.482 (2) Å in mol­ecule B compared to a mean bond length of 1.470 Å for a typical conjugated system (Bürgi & Dunitz, 1994 ▸). In addition, the C2—C1—C10 bond angle increases to 130.6 (2)° in both mol­ecules, and the pyrazole and phenyl rings are twisted with respect to each other, with torsion angle C2—C1—C10—C11 being 18.1 (3)° in mol­ecule A and −14.3 (3)° in mol­ecule B.

There is an even stronger repulsion between the amino­chloro­phenyl and pyrazole rings linked through the bridging amino group [shortened intra­molecular contacts are: C2⋯C9 = 3.25 Å (A), 3.21 Å (B); C2⋯H9 = 2.75 Å (A), 2.67 Å (B); H3⋯H4 = 2.28 Å for both mol­ecules; C3⋯H9 = 2.76 Å for both mol­ecules] leads to a greater twist of these unsaturated rings relative to each other; the dihedral angle between the mean planes n class="Chemical">N1/N2/C1–C3 and C4–C9 is 46.6 (1)° for mol­ecule A and 40.0 (1)° for B. Moreover, the N3—C3 bonds [1.395 (3) Å in A and 1.394 (2) Å in B; mean value of 1.339 Å] and the N3—C4 bonds [1.408 (2) Å in A, 1.406 (2) Å in B; mean value of 1.353 Å] are elongated with respect to the mean values for such bonds, and the C2=C3—N3 bond angle is increased to 130.3 (2)° in A and 130.5 (2)° in B. The bridging nitro­gen atom, N3, has an almost planar configuration (the bond-angle sum is 356° in A and 358° in B). The n class="Chemical">N4H2 amino group has a pyramidal configuration (bond-angle sum is 329° in A and 325° in B). The C5—N4 bond, 1.422 (3) Å in A and 1.425 (3) Å in B, is elongated in comparison with the mean value of 1.394 Å; this elongation is probably caused by the involvement of the nitro­gen lone pair in hydrogen bonding (Table 1 ▸).

Supra­molecular features

In the crystal, mol­ecules are linked by two pairs of N—H⋯n class="Chemical">N hydrogen bonds, forming A–B dimers (Table 1 ▸ and Fig. 3 ▸). The dimers are linked by a fifth N—H⋯N hydrogen bond to form a tetra­mer-like arrangement (Table 1 ▸ and Fig. 3 ▸). These stack up the a-axis direction, forming columns (Table 2 ▸ and Fig. 4 ▸), which are linked by C—H⋯π inter­actions, forming layers parallel to the ac plane.

Database survey

A search of the Cambridge Structural Database (Version 5.38, update February 2017; Groom et al., 2016 ▸) for N,5-diphenyl-1H-pyrazol-3-amine (S1; Fig. 5 ▸) gave only two relevant hits, viz. methyl 3-nitro-4-[(5-phenyl-n class="Chemical">1H-pyrazol-3-yl)amino]­benzo­ate (DIKSOG; Portilla et al., 2007 ▸) and N-(5-phenyl-1H-pyrazol-3-yl)benzene-1,2-di­amine (KUTFAH; Doumbia et al., 2010 ▸). They differ from compound (Ib) in the substituents on one of the aromatic rings (see Fig. 5 ▸). The mol­ecule of DIKSOG is practically planar, probably owing to the formation of intra­molecular N—H⋯O and C—H⋯N hydrogen bonds. In compound KUTFAH, while the phenyl ring is almost coplanar with the pyrazole ring (dihedral angle is ca 3.68° cf. 2.15° in DIKSOG), the o-amino­phenyl ring is inclined to the pyrazole ring by ca 64.03° (cf. 5.61° in DIKSOG). This conformation is similar to that of compound (Ib). In the crystal of DIKSOG, mol­ecules are linked by pairs of N—H⋯N hydrogen bonds, forming inversion dimers, while in the crystal of KUTFAH, mol­ecules are linked into chains by N—H⋯N hydrogen bonds.

Synthesis and crystallization

The initial 4-phenyl-1,3-di­hydro-2H-benzo[b][1,4]diazepine-2-thio­nes (IIa) and (IIb) were synthesized from the corres­ponding 4-phenyl-1,3-di­hydro-n class="Chemical">2H-benzo[b][1,4]diazepin-2-ones according to the procedure described previously (Solomko et al., 1990 ▸). The synthesis of the title compound (Ib) is illustrated in Fig. 1 ▸. General procedure: Hydrazine hydrate (0.5 ml, 85% n class="Chemical">aq. solution) was added to a solution of the corresponding 4-phenyl-1,3-di­hydro-2H-benzo[b][1,4]diazepine-2-thio­nes, (IIa) or (IIb), (5 mmol) in ethanol (40 ml). The mixture was heated at reflux for 3 h (TLC monitoring), then the solvent and the excess of hydrazine hydrate were removed under reduced pressure. The residue was washed with small amounts of cold alcohol. Colourless crystals of (Ia) and (Ib) were grown by recrystallization of the crude product from ethanol solution.
