N′-[4-(2-Furyl)but-3-en-2-ylidene]isonicotinohydrazide
The mol-ecule of the title Schiff base compound, C(14)H(13)N(3)O(2), is not perfectly planar; the furyl and pyridine rings are twisted with respect to each other along the C(4)N(2)C(2) organic chain, making a dihedral angle of 13.3 (1)°. The occurence of N-H⋯O hydrogen bonds builds up a chain developing parallel to the c axis.
متن کامل(E)-2-Phenyl-N-tosylnon-2-en-4-ynamide
The mol-ecule of the title compound, C22H23NO3S, adopts an E conformation about the C=C bond. The dihedral angle between the benzene rings is 23.79 (5)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules, forming inversion dimers. The terminal butyl group is disordered over two sets of sites in a 0.559 (6):0.441 (6) ratio.
متن کاملDimethyl (2-hydroxy-4-phenylbut-3-en-2-yl)phosphonate
In the title compound, C(12)H(17)O(4)P, the phenyl-butenyl group is disordered over two sets of sites with an occupancy ratio of 0.755 (12):0.245 (12). In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds occur, forming R(2) (2)(10) ring motifs. The packing is consolidated by weak C-H⋯π inter-actions.
متن کامل4-(2-Methylanilino)pent-3-en-2-one
The title enamino ketone, C(12)H(15)NO, a derivative of 4-(phenyl-amino)-pent-3-en-2-one, presents a roughly planar [greatest displacement of an atom from the pentenone plane is 0.033 (2) Å] pentenone backbone, enhanced by an intra-molecular N-H⋯O hydrogen bond; the asymmetry in C-C distances in the group suggests the presence of unsaturated bonds. The overall geometry in the free ligand differ...
متن کامل4-(2-Chlorophenylamino)-pent-3-en-2-one
In the title compound, C(11)H(12)ClNO, intra-molecular N-H⋯O hydrogen bonding is present. The dihedral angle between the benzene ring and the pentenone unit is 46.52 (5)°. In the crystal, C-H⋯O inter-actions between hydrogen atoms of the aryl moiety and two separate oxygen atoms occur, leading to a three-dimensional network.
