N-(2-Methyl-phen-yl)-6-(1H-pyrazol-1-yl)pyridazin-3-amine.

ABSTRACT: 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.

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)°.

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.

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

Project description: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.

Project description:The five-membered ring of the title compound, C(11)H(9)ClF(3)N(3), is almost planar (r.m.s. deviation = 0.002 Å) and the phenyl-ene ring is aligned at 44.8 (1)°. The N atom of the amino substituent shows a pyramidal geometry and is a hydrogen-bond donor to a Cl atom and to a ring N atom, which together generate a layer motif.

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.

A monoclinic polymorph of 4-(2H-1,3-benzodioxol-5-yl)-1-(4-methyl-phen-yl)-1H-pyrazol-5-amine.

Project description:The title compound, C17H15N3O2, is a monoclinic polymorph (P21/c with Z' = 1) of the previously reported triclinic (P-1 with Z' = 2) form [Gajera et al. (2013 ▸). Acta Cryst. E69, o736-o737]. The mol-ecule in the monoclinic polymorph features a central pyrazolyl ring with an N-bound p-tolyl group and a C-bound 1,3-benzodioxolyl fused-ring system on either side of the C atom bearing the amino group. The dihedral angles between the central ring and the N- and C-bound rings are 50.06 (5) and 27.27 (5)°, respectively. The angle between the pendent rings is 77.31 (4)°, indicating the mol-ecule has a twisted conformation. The five-membered dioxolyl ring has an envelope conformation with the methyl-ene C atom being the flap. The relative disposition of the amino and dioxolyl substituents is syn. One of the independent mol-ecules in the triclinic form has a similar syn disposition but the other has an anti arrangement of these substituents. In the crystal structure of the monoclinic form, mol-ecules assemble into supra-molecular helical chains via amino-pyrazolyl N-H⋯N hydrogen bonds. These are linked into layers via C-H⋯π inter-actions, and layers stack along the a axis with no specific inter-actions between them.

(E)-3-(4-Methyl-phen-yl)-3-[3-(4-methyl-phen-yl)-1H-pyrazol-1-yl]-2-propenal.

Project description:In the title compound, C(20)H(18)N(2)O, the pyrazole ring adopts a planar conformation. The C-N bond lengths in the pyrazole ring are shorter than a standard C-N single bond (1.443 Å), but longer than a standard double bond (1.269 Å), indicating electron delocalization. The propenal group assumes an extended conformation. Inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into cyclic centrosymmetric R(2) (2)(26) dimers, which are cross-linked via C-H⋯π inter-actions.

In addition, a weak C-H?N inter-action is observed.

5-Methyl-1-[(4-methyl-phen-yl)sulfon-yl]-1H-pyrazol-3-yl 4-methyl-benzene-sulfonate.

Project description:In the title compound, C(18)H(18)N(2)O(5)S(2), the tolyl rings are oriented at a dihedral angle of 16.15 (11)° with respect to one another. The 5-methyl-1H-pyrazol-3-ol ring is roughly planar (r.m.s. deviation = 0.0231 Å) and subtends angles of 73.82 (8) and 89.85 (8)° with the tolyl rings. In the crystal, very weak π-π inter-actions between tolyl groups, with centroid-centroid distances of 4.1364 (19) and 4.0630 (16) Å, together with a C-H⋯π contact generate a three-dimensional network.
