Background:

• Understanding molecular conformation and crystal packing is crucial for designing new materials.
• Hydrogen bonding plays a significant role in stabilizing crystal structures and influencing material properties.

Purpose of the Study:

• To determine the crystal structure of the title compound, C(9)H(11)N(2)O(4) (+)·ClO(4) (-).
• To investigate the role of intra-molecular and inter-molecular hydrogen bonding in stabilizing the crystal conformation and packing.

Main Methods:

• Single-crystal X-ray diffraction was used to analyze the crystal structure.
• Hydrogen bonding interactions (N-H⋯O, O-H⋯O, C-H⋯O) were identified and analyzed.

Main Results:

• The crystal structure revealed an intra-molecular N-H⋯O hydrogen bond stabilizing the cation conformation.
• Inter-molecular O-H⋯O hydrogen bonds between carboxyl groups formed dimers.
• Dimers and perchlorate anions were organized into layers via C-H⋯O and N-H⋯O interactions.

Conclusions:

• The crystal structure is stabilized by a combination of intra-molecular and inter-molecular hydrogen bonds.
• The observed hydrogen bonding network dictates the formation of dimers and layered structures.
• This detailed structural analysis provides a foundation for understanding the compound's properties and potential applications.
