Purpose of the Study:

• To characterize the crystal structure of a specific hydrazone compound (C(15)H(13)N(3)O(3)·CH(3)OH).
• To investigate the molecular geometry, including configuration and planarity.
• To elucidate the intermolecular interactions and crystal packing in the methanol solvate.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of bond lengths, bond angles, and dihedral angles provided geometric information.
• Identification of hydrogen bonding networks and crystal packing arrangements.

Main Results:

• The hydrazone compound crystallized as a methanol solvate.
• The molecule possesses an E configuration around the C=N bond.
• The hydrazone core is nearly planar, with a small dihedral angle (5.3°) between the benzene rings.
• Hydrogen bonds (N-H⋯O and O-H⋯O) involving the methanol molecule link hydrazone units into chains along the a-axis.

Conclusions:

• The crystal structure of the title hydrazone solvate has been successfully determined.
• The observed molecular geometry and hydrogen bonding pattern dictate the formation of 1D chains in the solid state.
• This structural information provides a foundation for further studies on the properties and potential applications of this hydrazone derivative.
