N'-(2-Furylmethyl-ene)nicotinohydrazide.

Area of Science:

• Crystallography
• Organic Chemistry
• Molecular Structure

Background:

• Understanding the molecular arrangement and intermolecular interactions of organic compounds is crucial for predicting their physical and chemical properties.
• The specific compound C(11)H(9)N(3)O(2) presents an interesting case for structural analysis due to its heterocyclic components.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(11)H(9)N(3)O(2).
• To determine the precise spatial arrangement of the independent molecules within the asymmetric unit.
• To identify and characterize the intermolecular interactions, specifically hydrogen bonds, present in the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
• Analysis of the crystal structure data to identify independent molecules and their relative orientations.
• Geometric analysis to measure dihedral angles between the pyridine and furyl rings.
• Identification and analysis of intermolecular hydrogen bonds (C-H⋯O, N-H⋯N, N-H⋯O).

Main Results:

• The asymmetric unit contains two independent molecules of C(11)H(9)N(3)O(2).
• The dihedral angles between the pyridine and furyl rings were found to be 17.00(16)° and 34.12(15)° for the two independent molecules, respectively.
• The crystal structure is stabilized by intermolecular hydrogen bonds, including C-H⋯O, N-H⋯N, and N-H⋯O interactions.

Conclusions:

• The crystal structure of C(11)H(9)N(3)O(2) has been successfully determined.
• The observed dihedral angles indicate distinct conformations for the two independent molecules.
• Intermolecular hydrogen bonding plays a significant role in the packing and stability of the crystal lattice.
