2-[2-(4-Nitro-phen-yl)hydrazinyl-idene]-1,3-diphenyl-propane-1,3-dione.

ABSTRACT: In the mol-ecular structure of the title compound, C(21)H(15)N(3)O(4), the inter-planar angle between the benzoyl units is 89.7?(1)°. The corresponding angles between the phenyl-hydrazono and the benzoyl groups are 31.4?(3) and 60.8?(2)°, respectively. In the crystal, a strong resonance-assisted intra-molecular hydrogen bond (N-H?O) and a weak intra-molecular hydrogen bond (C-H?N) strongly affect the observed conformation of the mol-ecule. The crystal packing is determined by a strong inter-molecular hydrogen bond (N-H?O), giving rise to a helical chain along the a axis. In addition, two weak inter-molecular contacts (C-H?O) are observed.

In the mol-ecular structure of the title compound, C(21)H(15)N(3)O(4), the inter-planar angle between the benzoyl units is 89.7 (1)°. The corresponding angles between the phenyl-hydrazono and the benzoyl groups are 31.4 (3) and 60.8 (2)°, respectively. In the crystal, a strong resonance-assisted intra-molecular hydrogen bond (N-H⋯O) and a weak intra-molecular hydrogen bond (C-H⋯N) strongly affect the observed conformation of the mol-ecule. The crystal packing is determined by a strong inter-mole ...[more]

Project description:In the title compound, C(23)H(18)N(2)O(3), the inter-planar angle between the benzoyl units is 80.51?(6)° while the dihedral angles between the hydrazinyl-idene and benzoyl groups are 43.43?(6) and 54.16?(6)°.

The mol-ecules form an inversion dimer via a pair of weak C-H?O hydrogen bonds and a ?-? inter-action [centroid-centroid distance of 3.5719?(10)?Å]. These dimers are linked via weak C-H?O contacts, forming chains along the b axis.

A second monoclinic polymorph of 2-[2-(4-meth-oxy-phen-yl)hydrazinyl-idene]-1,3-diphenyl-propane-1,3-dione.

Project description:The title compound, C(22)H(18)N(2)O(3) is the second monoclinic polymorph (P2(1)/c) of the compound, the first being reported in space group P2(1) [Bertolasi et al. (1993 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 2223-2228]. In the mol-ecular structure of the title compound, the inter-planar angle between the benzoyl units is 80.04 (5)°, while the corresponding angles between the phenyl-hydrazinyl-idene and benzoyl groups are 36.11 (5) and 55.77 (2)°. A strong resonance-assisted intra-molecular N-H⋯O hydrogen bond is found. In the crystal, the entire supra-molecular structure is constructed by weak inter-molecular C-H⋯O inter-actions and an inter-ring π-π inter-action [centroid-centroid distance = 3.6088 (8) Å].

2,2-Dimethyl-5-{[(4-nitro-phen-yl)amino]-methyl-idene}-1,3-dioxane-4,6-dione.

Project description:In the title compound, C(13)H(12)N(2)O(6), the dihedral angle between the benzene ring and the amino-methyl-ene unit is 5.42?(16)°, while the angle between the amino-methyl-ene unit and the dioxane ring is 3.06?(43)°. The dioxane ring shows a half-boat conformation, in which the C atom between the dioxane ring O atoms is 0.464?(10)?Å out of the plane. An intra-molecular N-H?O hydrogen bond stabilizes the mol-ecular conformation. In the crystal, a three-dimensional framework is built up via inter-molecular N-H?O hydrogen bonds.

(E)-1-(4-Nitro-phen-yl)-2-(4-{[(E)-2-(4-nitro-phen-yl)hydrazinyl-idene]meth-yl}benzyl-idene)hydrazine dihydrate.

Project description:The 30 non-H atoms in title dihydrazine compound, C(20)H(16)N(6)O(4)·2H(2)O, are close to coplanar, the r.m.s. deviation for these atoms being 0.096?Å. The conformation about each of the C=N bonds is E, and the mol-ecule has non-crystallographic 2/m symmetry. The presence of O-H?O and N-H?O hydrogen bonding leads to a three-dimensional network in the crystal structure. A highly disordered solvent mol-ecule is present within a mol-ecular cavity defined by the organic and water mol-ecules. Its contribution to the electron density was removed from the observed data in the final cycles of refinement and the formula, molecular weight and density are given without taking into account the contribution of the solvent molecule.

The dimers are further connected through slipped π-π inter-actions between symmetry-related benzene rings [centroid-centroid distance of 3.646 (1) Å, offset angle of 15.4°].
