Crystal structures and Hirshfeld surface analyses of (E)-N'-benzyl-idene-2-oxo-2H-chromene-3-carbo-hydrazide and the disordered hemi-DMSO solvate of (E)-2-oxo-N'-(3,4,5-trimeth-oxybenzyl-idene)-2H-chromene-3-carbohydrazide: lattice energy and inter-molecular inter-action energy calculations for the former.

ABSTRACT: The crystal structures of the disordered hemi-DMSO solvate of (E)-2-oxo-N'-(3,4,5-tri-meth-oxy-benzyl-idene)-2H-chromene-3-carbohydrazide, C₂₀H₁₈N₂O₆·0.5C₂H₆OS, and (E)-N'-benzyl-idene-2-oxo-2H-chromene-3-carbohydrazide, C₁₇H₁₂N₂O₃ (4: R = C₆H₅), are discussed. The non-hydrogen atoms in compound [4: R = (3,4,5-MeO)₃C₆H₂)] exhibit a distinct curvature, while those in compound, (4: R = C₆H₅), are essential coplanar. In (4: R = C₆H₅), C-H⋯O and π-π intra-molecular inter-actions combine to fo
