N-Phenyl-6-(1H-pyrazol-1-yl)pyridazin-3-amine.

ABSTRACT: The mol-ecule of title compound, C(13)H(11)N(5), is essentially planar (r.m.s. deviation = 0.0440?Å) and an intra-molecular C-H?N hydrogen bond generates an S(6) motif. In the crystal, mol-ecules are connected into chains by inter-molecular N-H?N and C-H?N hydrogen bonds. In addition, ?-? stacking inter-actions are observed between the pyrazole and pyridazine rings [inter-planar distance = 3.6859?(10)?Å].

The mol-ecule of title compound, C(13)H(11)N(5), is essentially planar (r.m.s. deviation = 0.0440 Å) and an intra-molecular C-H⋯N hydrogen bond generates an S(6) motif. In the crystal, mol-ecules are connected into chains by inter-molecular N-H⋯N and C-H⋯N hydrogen bonds. In addition, π-π stacking inter-actions are observed between the pyrazole and pyridazine rings [inter-planar distance = 3.6859 (10) Å]. ...[more]

Project description:The title compound, C(14)H(13)N(5), crystallizes with two crystallographically independent mol-ecules in the unit cell. The two mol-ecules form dimers through inter-molecular N-H?N and C-H?N hydrogen bonds. The hydrogen-bonding motifs are R(2) (2)(8) for both the N-H?N and C-H?N inter-actions. The pyrazole and pyrimidine rings form dihedral angles of 6.2?(3) and 8.3?(3)° with each other and the dihedral angles between the pyrazole and benzene rings are 54.9?(2) and 58.6?(2)°. The benzene rings of neighbouring dimers also exhibit C-H?? inter-actions.

N-(4-Methyl-phen-yl)-6-(pyrazol-1-yl)pyridazin-3-amine.

Project description:In the title compound, C(14)H(13)N(5), the pyrazole ring is disordered over two orientations in a 0.571?(10):0.429?(10) ratio and the dihedral angle between the pyridazine ring and the benzene ring is 28.07?(10)°. In the crystal, pairs of N-H?N and C-H?N hydrogen bonds link the mol-ecules into dimers, with the aid of a crystallographic twofold axis. The packing is consolidated by further C-H?N bonds and weak C-H?? inter-actions.

5-Chloro-1-phenyl-1H-pyrazol-4-amine.

Project description:In the crystal structure of the title compound, C(9)H(8)ClN(3), amino-pyrazole N-H?N hydrogen bonds connect the mol-ecules along the [010] direction; the chains interact with each other only by van der Waals-type inter-actions.

4-(2H-1,3-Benzodioxol-5-yl)-1-(4-methyl-phenyl)-1H-pyrazol-5-amine.

Project description:In the title compound, C17H15N3O2, two independent mol-ecules (A and B) comprise the asymmetric unit. The major conformational difference arises in the relative orientation of the pyrazole ring amine and dioxole substituents which are anti in A and syn in B. The five-membered dioxole ring in each mol-ecule has an envelope conformation with the methyl-ene C atom as the flap. The mean plane through the benzodioxole and benzene groups make dihedral angles of 31.67?(8) and 68.22?(9)°, respectively, with the pyrazole ring in A; the equivalent values for B are 47.18?(7) and 49.08?(9)°. In the crystal, supra-molecular zigzag chains along the b-axis direction arise as a result of N-H?N hydrogen bonding. These are consolidated into supra-molecular double chains via C-H?O and C-H?? inter-actions.

Crystal structure of (E)-N-{[3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]methyl-idene}hydroxyl-amine.

Project description:The title compound, C15H14N4O, crystallizes with two mol-ecules in the asymmetric unit with similar conformations (r.m.s. overlay fit for the 20 non-H atoms = 0.175?Å). In the first mol-ecule, the dihedral angles between the planes of the central pyrazole ring and the pendant phenyl and pyrrole rings are 42.69?(8) and 51.88?(6)°, respectively, with corresponding angles of 54.49?(7) and 49.61?(9)°, respectively, in the second mol-ecule. In the crystal, the two mol-ecules, together with their inversion-symmetry counterparts, are linked into tetra-mers by O-H?N hydrogen bonds. The tetra-mers form layers parallel to (211) through pairwise C-H?? inter-actions.

1-(4-Methoxy-phen-yl)-3-phenyl-1H-pyrazol-5-amine.

Project description:The synthesis of the title compound, C(16)H(15)N(3)O, is regiospecific and single-crystal X-ray diffraction provides the only means of unambiguous structural analysis, with the benzene ring bonded to the imine C atom. The phenyl ring and the essentially planar (r.m.s. deviation 0.0354?Å) methoxy-benzene group are rotated by 29.41?(5) and 37.01?(5)°, respectively, from the central pyrazole ring. An inter-molecular N-H?N hydrogen bond links symmetry-related mol-ecules into a C(5) chain, which runs parallel to the b axis.

4-[(5-Hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)phenyl-meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol hemisolvate.

Project description:The asymmetric unit of the title compound, C(27)H(24)N(4)O(2)·0.5C(2)H(6)O, comprises two crystallographically independent mol-ecules (A and B) with slightly different conformations, and one ethanol mol-ecule of crystallization. Intra-molecular C-H⋯O and O-H⋯O hydrogen bonds generate six- and eight-membered rings, producing S(6) and S(8) ring motifs, respectively. In mol-ecule A, one of the benzene rings is disordered over two positions, with site-occupancy factors of 0.542 (11) and 0.458 (11). The dihedral angles between the central benzene ring and the two outer benzene rings are 73.88 (9) and 82.6 (2)/88.9 (2)° in mol-ecule A, and 80.81 (8) and 79.38 (8)° in mol-ecule B. In the crystal structure, mol-ecules form infinite one-dimensional chains in the (101) plane. The crystal structure is stabilized by inter-molecular O-H⋯N, N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, weak C-H⋯π and π-π [centroid-centroid = 3.5496 (1) Å] inter-actions.

Project description:In the title compound, C(23)H(17)N(5)·H(2)O, the pyrazole rings are slightly twisted from the central pyridine ring, forming dihedral angles of 5.3?(2) and 3.5?(2)°.
