(E)-N'-Hy-droxy-1,3-diphenyl-4,5-di-hydro-1H-pyrazole-5-carboximidamide.

ABSTRACT: In the mol-ecule of the title compound, C(16)H(16)N(4)O, the pyrazole ring makes dihedral angles of 8.52?(13) and 9.26?(12)° with the phenyl rings. The dihedral angle between the benzene rings is 1.86?(13)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H?N hydrogen bonds. Weak N-H?N inter-actions connect the dimers into a chain along the [100] direction. The pyrazole ring adopts a highly flattened envelope conformation.

Project description:The title compound, C(30)H(24)N(4), contains two pyrazole rings and four phenyl rings.

In the crystal, there are no significant inter-molecular hydrogen-bonding inter-actions. The crystal structure is stabilized by C-H⋯π inter-actions.

Crystal structure and Hirshfeld surface analysis of 5-(3,5-di-tert-butyl-4-hy-droxy-phen-yl)-3-phenyl-4,5-di-hydro-1H-pyrazole-1-carboxamide.

Project description:In the title compound, C24H31N3O2, the mean plane of the central pyrazole ring [r.m.s. deviation = 0.095?Å] makes dihedral angles of 11.93?(9) and 84.53?(8)°, respectively, with the phenyl and benzene rings. There is a short intra-molecular N-H?N contact, which generates an S(5) ring motif. In the crystal, pairs of N-H?O hydrogen bonds link inversion-related mol-ecules into dimers, generating an R 2 2(8) ring motif. The Hirshfeld surface analysis indicates that the most significant contribution involves H?H contacts of 68.6.

3-Oxo-N',2-diphenyl-2,3-di-hydro-1H-pyrazole-4-carbohydrazide.

Project description:In the title compound, C16H14N4O2, the pyrazole ring makes a dihedral angle of 10.49?(8)° with its N-bound phenyl group, while it is nearly perpendicular to the other phenyl ring [dihedral angle = 88.47?(5)°]. The mol-ecular conformation is stabilized by intra-molecular C-H?O and N-H?O hydrogen bonds. In the crystal, the packing involves sheets of mol-ecules parallel to (100) linked by N-H?O hydrogen bonds. A C-H?O interaction is also observed.

1,3-Diphenyl-1H-pyrazole-4-carbaldehyde.

Project description:There are four mol-ecules in the asymmetric unit of the title compound, C(16)H(12)N(2)O. The dihedral angle between the phenyl rings in the mol-ecules are 22.2?(2), 22.4?(2), 25.1?(3) and 41.9?(2)°. In the crystal, mol-ecules form dimers due to inter-molecular C-H?O hydrogen bonds, which result in one R(2) (2)(10) and two R(2) (1)(7) ring motifs. Weak aromatic ?-? stacking [centroid-centroid separation = 3.788?(3)?Å] and C-H?? inter-actions may also consolidate the packing.

Crystal structure of 2-(5-bromo-2-hy-droxy-benzyl-idene)-2,3-di-hydro-1H-indene-1,3-dione.

Project description:The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02?(9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47?(9)° between the planes of the five- and six-membered rings. An intra-molecular C-H?O hydrogen bond between the attached benzene ring with one of the indandione carbonyl O atoms stabilizes the mol-ecular conformation. In the crystal, the mol-ecules form dimers across centres of inversion via pairwise O-H?O hydrogen bonds. The dimers form stacks running parallel to [010] and inter-act through ?-? inter-actions between the five-membered ring of one mol-ecule and the six-membered rings of the indandione moiety of an adjacent mol-ecule [centroid-to-centroid distance = 3.5454?(10)?Å].

Crystal structure of methyl 2-hy-droxy-5-[(4-oxo-4,5-di-hydro-1,3-thia-zol-2-yl)amino]benzoate.

Project description:The title compound, C11H10N2O4S, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. They differ primarily in the rotational orientation of the five-membered heterocyclic ring. In mol-ecule A this ring is inclined to the benzene ring by 48.17?(8)°, while in mol-ecule B the same dihedral angle is 23.07?(8)°. In each mol-ecule there is an intra-molecular O-H?O hydrogen bond involving the adjacent hydroxyl group and the ester carbonyl O atom. In the crystal, the A mol-ecules are linked via pairs of N-H?N hydrogen bonds, forming inversion dimers. These dimers are linked to the B mol-ecules via N-H.·O, C-H?O and C-H?S hydrogen bonds forming corrugated sheets lying parallel to (102).
