Background:

• Schiff bases are versatile organic compounds with diverse applications.
• Understanding the solid-state structure of Schiff bases is crucial for predicting their properties and designing new materials.
• Hydrogen bonding plays a significant role in the self-assembly and stability of molecular crystals.

Purpose of the Study:

• To elucidate the detailed molecular and crystal structure of the Schiff base compound C(15)H(14)N(2)O(3)·H(2)O.
• To investigate the role of hydrogen bonding in stabilizing the molecular and crystal architecture.
• To characterize the supramolecular arrangement of the Schiff base and water molecules in the solid state.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
• Analysis of bond lengths, bond angles, and dihedral angles provided insights into molecular geometry.
• Intermolecular and intramolecular interactions, particularly hydrogen bonds, were identified and analyzed.

Main Results:

• The Schiff base molecule is approximately planar, with a dihedral angle of 10.2° between its two aromatic rings.
• Intramolecular hydrogen bonds (O-H⋯N and N-H⋯O) stabilize the Schiff base molecule.
• Intermolecular O-H⋯O hydrogen bonds link Schiff base and water molecules, forming chains along the a-axis in the crystal structure.

Conclusions:

• The crystal structure of C(15)H(14)N(2)O(3)·H(2)O reveals a planar Schiff base stabilized by intramolecular hydrogen bonds.
• The formation of 1D chains through intermolecular hydrogen bonding highlights the role of water in crystal engineering.
• This structural information provides a foundation for exploring potential applications of this Schiff base derivative.
