Crystal structure and Hirshfeld surface analysis of (E)-4-amino-N′-[1-(4-methylphenyl)ethylidene]benzohydrazide
The structure of the title Schiff base, C16H17N3O, displays a trans configuration with respect to the C=N double bond, with a dihedral angle of 14.98 (9)° between the benzene rings. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, giving sheets extending across the (001) plane. Hirshfeld surface analysis gave fingerprint plots showing enrichment ratios fo...
متن کاملCrystal structure and Hirshfeld surface analysis of pulcherrin J
The title compound, C29H36O4 [systematic name (4aR,5R,6aS,7R,11aS,11bR)-4a-hydroxy-4,4,7,11b-tetramethyl-1,2,3,4,4a,5,6,6a,7,11,11a,11b-dodecahydrophen-anthro[3,2-b]furan-5-yl cinnamate], a natural diterpene known as pulcherrin J, was isolated from stem barks of medicinally important Caesalpinia pulcherrima (L.). The crystal structure of pulcherrin J shows it to be composed of a central core of...
متن کاملm-Xylylenediaminium sulfate: crystal structure and Hirshfeld surface analysis
The crystal structure of the title salt {systematic name: [1,3-phenyl-enebis(methyl-ene)]bis-(aza-nium) sulfate}, C8H14N2 (2+)·SO4 (2-), consists of infinite (100) sheets of alternating organic and inorganic entities The m-xylylenediaminium cations are linked to the sulfate anions by N-H⋯O and asymmetric bifurcated N-H⋯(O,O) hydrogen bonds, generating a three-dimensional network. A weak C-H⋯O i...
متن کاملTwo dialkylammonium salts of 2-amino-4-nitrobenzoic acid: crystal structures and Hirshfeld surface analysis
The crystal structures of two ammonium salts of 2-amino-4-nitro-benzoic acid are described, namely di-methyl-aza-nium 2-amino-4-nitro-benzoate, C2H8N+·C7H5N2O4-, (I), and di-butyl-aza-nium 2-amino-4-nitro-benzoate, C8H20N+·C7H5N2O4-, (II). The asymmetric unit of (I) comprises a single cation and a single anion. In the anion, small twists are noted for the carboxyl-ate and nitro groups from the ...
متن کاملCrystal structure of 2-oxo-2H-chromen-3-yl 4-chlorobenzoate and Hirshfeld surface analysis
In the title compound, C16H9ClO4 the dihedral angle between the coumarin ring system [maximum deviation = 0.023 (1) Å] and the benzene ring is 73.95 (8)°. In the crystal, π-π inter-actions link the dimers into a three-dimensional framework. A quantum chemical calculation is in generally good agreement with the observed structure, although the calculated dihedral angle between the ring systems (...
