(E)-1-[1-(6-Bromo-2-oxo-2H-chromen-3-yl)ethylidene]thiosemicarbazide
The title compound, C(12)H(10)BrN(3)O(2)S, exists in an E configuration with respect to the C=N bond. The approximately planar 2H-chromene ring system [maximum deviation = 0.059 (1) Å] is inclined at a dihedral angle of 17.50 (5)° with respect to the mean plane through the thio-semicarbazide unit and an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring. In the crystal structure, adjace...
متن کامل2-Cyano-N′-[(E)-1-(2-oxo-2H-chromen-3-yl)ethylidene]acetohydrazide
In the title compound, C(14)H(11)N(3)O(3), the chromene ring is almost planar, with a maximum deviation of 0.065 (2) Å from the mean plane for one of the C atoms. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. The dimers are linked by C-H⋯N and C-H⋯O inter-actions into a three-dimensional network. An aromatic π-π stacking inter-action, with ...

In the mol-ecule of the title compound, C(17)H(10)BrNO(5), the indoline system and the attached coumarin ring are each essentially planar with maximum deviations of 0.074 (2) and 0.062 (2) Å, respectively. The dihedral angle between them is 85.09 (3)°. In the crystal, all heteroatoms (except for the coumarin oxo O atoms) are involved in intra- and inter-molecular hydrogen bonds. An intra-molecu...
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl pyrrolidine-1-carbodithioate
There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the cr...

In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...
