Conclusions
-
1.
An x-ray diffraction structural study of crystals of N′-(5-nitrofurfurylidene)benzhydrazide revealed the first case of the cocrystallization of syn and syn-anti isomers of ketohydrazone molecules. We propose that the isomerization of the ketohydrazone molecules occurs upon crystallization and is a consequence of packing effects. The crystal structure of this ketohydrazone is a rare case of the laminar packing of polar and nonpolar molecular chains.

2.
The formation of hydrates of N′-(5-nitrofurfurylidene)hydrazides radically alters the structure of their frontier molecular orbitals in comparison with the anhydrous molecules. This may significantly affect the properties of the crystals of these compounds.
