2,4-Difluorobenzaldehyde benzoylhydrazone and 2,4-dichlorobenzaldehyde benzoylhydrazone are isostructural at 120 K with Z' = 2: complex sheets built from N-HO, C-HO and C-H(arene) hydrogen bonds

Abstract: At 120 K, 2,4-difluorobenzaldehyde benzoylhydrazone, C₁₄H₁₀F₂N₂O, (I), and 2,4-dichlorobenzaldehyde benzoylhydrazone, C₁₄H₁₀Cl₂N₂O, (II), are isomorphous and isostructural in P2₁/n with Z' = 2. In each structure, eight independent hydrogen bonds, viz. two of N-HO type, five of C-HO type and one of C-H [pi] (arene) type, link the molecules into complex sheets, within which two independent one-dimensional substructures can be identified.

Formula: C₁₄H₁₀F₂N₂O and C₁₄H₁₀Cl₂N₂O
