2-Cyano-N'-[(E)-1-(2-oxo-2H-chromen-3-yl)ethyl-idene]acetohydrazide.

ABSTRACT: 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 ?-? stacking inter-action, with a centroid-centroid distance of 3.562?(10)?Å, is also observed.

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 a centroid-centroid distance of 3.562 (10) Å, is also observed. ...[more]

Project description: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 crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds occur for one of the mol-ecules. Further C-H?O links involving both mol-ecules generate a three-dimensional network.

Project description: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.

These chains are further inter-connected into sheets parallel to the ab plane via short Br?O inter-actions [3.0732?(13)?Å] and a ?-? aromatic stacking inter-action [3.7870?(8)?Å] is also observed.
