Crystal structure of 2-[(2E)-2-methyl-3-phenyl-prop-2-en-1-yl-idene]-N-phenyl-hydrazinecarboxamide.

ABSTRACT: The title compound, C₁₇H₁₇N₃O, crystallizes with two independent mol-ecules in the asymmetric unit. The semicarbazone moieties of these independent mol-ecules (I and II) are essentially planar [maximum deviation of 0.042?(1)?Å in mol-ecule I and 0.041?(1)?Å in mol-ecule II], with the terminal phenyl rings twisted away from the mean plane of the semicarbazone moiety, making dihedral angles of 60.26?(8) and 28.76?(9)° in mol-ecule I and 31.07?(9) and 35.45?(8)° in mol-ecule II. The mol-ecules both exhibit an E configuration with respect to the C=C and azomethine C=N bonds. In the crystal, two classical N-H?O hydrogen-bonding inter-actions are present between the two mol-ecules, forming a centrosymmetric dimer, while a weak C-H?O non-classical hydrogen-bonding inter-action, with a donor-acceptor distance of 3.476?(2)?Å, inter-connects two neighbouring centrosymmetric dimers to form a cage-like structure. These cage structures are inter-connected by weak C-H?? inter-actions with an H?? distance of 2.790?Å, forming supra-molecular chains along the c-axis direction.
