(E)-N'-[(E)-3-(4-Hydr-oxy-3-methoxy-phen-yl)allyl-idene]isonicotinohydrazide

Area of Science:

• Crystallography
• Organic Chemistry
• Materials Science

Background:

• Understanding molecular interactions is crucial for designing new materials.
• Crystal packing influences material properties and reactivity.

Purpose of the Study:

• To characterize the crystal structure of a novel organic compound.
• To elucidate the intermolecular forces governing its solid-state assembly.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of intermolecular interactions (hydrogen bonds, C-H···π) was performed.

Main Results:

• The compound C(16)H(15)N(3)O(3) exhibits a dihedral angle of 7.66° between pyridine and benzene rings.
• Intermolecular C-H⋯O and O-H⋯N interactions form zigzag chains along [010].
• These chains are further interconnected by N-H⋯O, C-H⋯N, C-H⋯O, and C-H⋯π interactions into a 3D network.

Conclusions:

• The crystal structure is stabilized by a combination of hydrogen bonding and van der Waals forces.
• The observed packing motif provides insights into the self-assembly behavior of related molecules.
• This detailed structural analysis contributes to the understanding of organic crystal engineering.
