Butane-2,3-dione bis[(4-bromobenzylidene)hydrazone]
The title compound, C(18)H(16)Br(2)N(4), is a linear double Schiff base compound having two parallel 4-bromo-phenyl groups connected across a crystallographic inversion centre by flexible C-C and C=N-N=C bonds and stabilized in the solid state by weak inter-molecular Br⋯Br inter-actions [3.7992 (11) Å], generating an infinite two-dimensional network structure.
متن کامل1,4-Bis(4-chlorophenyl)butane-1,4-dione
The mol-ecule of title compound, C(16)H(12)Cl(2)O(2), is centrosymmetric. Thus, the asymmetric unit comprises two half-mol-ecules. The two benzene rings are coplanar in each independent molecule (dihedral angles = 0°). The crystal packing exhibits inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
متن کاملCrystal structure of 1-(piperidin-1-yl)butane-1,3-dione
In the title compound, C9H15NO2, the piperidine ring exhibits a chair conformation. The butane-dione subunit exhibits a conformation with the ketone C atom in an eclipsed position with respect to the amide carbonyl group. In the crystal, a two-dimensional layered arrangement is formed by hydrogen bonds of the C-H⋯O type between the methyl group and the exocyclic methyl-ene unit as donor sites a...
متن کامل1,4-Bis(thiophen-2-yl)butane-1,4-dione
In the centrosymmetric title compound, C(12)H(10)O(2)S(2), the alkyl chains adopt a fully extended all-trans conformation with respect to the C(thio-phene)-C bond. The non-H atoms of the mol-ecule are nearly planar, with a maximum deviation of 0.063 (2) Å from the mean plane of the constituent atoms. In the crystal, symmetry-related mol-ecules are linked via pairs of C-H⋯π contacts [H-centroid ...
متن کاملButane-2,3-dione: the key contributor to axillary and foot odor associated with an acidic note.
Human body odor, which contains several volatile organic compounds, possesses various odor qualities. To identify key volatile compounds responsible for the common unpleasant odors derived from human axillae and feet, the odor quality and intensity of 118 human axillae and feet were directly evaluated by sniffing, and odor compounds obtained from the subjects were identified. Furthermore, the s...
