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

ABSTRACT: 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)°. In the crystal, a strong resonance-assisted intra-molecular N-H?O hydrogen bond is observed. 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.

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)°. In the crystal, a strong resonance-assisted intra-molecular N-H⋯O hydrogen bond is observed. The mol-ecules form an inversion dimer via a pair of weak C-H⋯O hydrogen bonds and a π-π inter-action [centroid-centroid distance of 3.5719 (10) Å]. These dimers are linked via weak C-H⋯O contacts, ...[more]

Project description:The mol-ecular structure of the title compound, C(21)H(15)ClN(2)O(2), features one strong intra-molecular N-H?O resonance-assisted hydrogen bond (RAHB). In the crystal, mol-ecules form inversion-related dimers via pairs of weak inter-molecular N-H?O contacts. These dimers are further stabilized via three weak C-H?O contacts, developing the three-dimensional structure.

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

Project description: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.

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].

1,3-Bis(4-fluoro-phen-yl)-N,N'-(propane-1,3-diyl-idene)dihydroxyl-amine.

Project description:The title compound, C(15)H(12)F(2)N(2)O(2), crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both aromatic rings of both mol-ecules are disordered over two orientations [occupancy ratios of 0.768?(3):0.232?(3) and 0.770?(3):0.230?(3) for mol-ecule A and 0.789?(3):0.211?(3) and 0.789?(3):0.211?(3) for mol-ecule B]. The dihedral angles between the planes of the major and minor components of the disordered aromatic rings are 72.0?(4) and 71.2?(4)° for mol-ecule A, and 70.2?(4) and 71.5?(2)° for mol-ecule B. In the crystal, both mol-ecules form inversion dimers with R(2) (2)(6) ring motifs via pairs of inter-molecular O-H?N hydrogen bonds. The dimers are linked, forming zigzag C(7) chains along the c axis. Weak C-H?? inter-actions help to consolidate the packing.

Project description:In the title compound, C17H12F2N2O2S2, the conformation of the dithia-cyclo-pentane ring is a half-chair, with a total puckering amplitude Q T = 0.460?(1)?Å. ?-? inter-actions [centroid-centroid distance = 3.585?(9)?Å between the fluoro-phenyl rings of neighbouring mol-ecules] and C-H?N and C-H?O inter-actions help to stabilize the crystal structure and form ladders along the c axis.

Weak non-classical C-H?X (X = O, N, Cl) inter-actions further consolidate the packing, forming a layer structure parallel to (110).
