Area of Science:

• Crystal engineering
• Supramolecular chemistry
• Organic solid-state chemistry

Background:

• Understanding molecular packing is crucial for designing new materials.
• Intermolecular forces dictate crystal lattice formation and properties.
• The C(11)H(6)N(2)O(2) molecule possesses a unique butterfly shape.

Purpose of the Study:

• To elucidate the crystal structure of the title compound.
• To investigate the intermolecular interactions governing its solid-state assembly.
• To characterize the supramolecular architecture.

Main Methods:

• Single-crystal X-ray diffraction analysis.
• Analysis of hydrogen bonding networks (C-H⋯O).
• Investigation of π-π stacking interactions.

Main Results:

• The molecule exhibits a slight fold with a dihedral angle of 6.42(3)°.
• Adjacent molecules form infinite layers via C-H⋯O hydrogen bonds parallel to the ac plane.
• A 3D network is established through π-π interactions between anti-parallel molecules (centroid-centroid distance: 3.4349(9) Å).

Conclusions:

• The crystal structure is stabilized by a combination of hydrogen bonding and π-π interactions.
• The observed supramolecular arrangement leads to a robust three-dimensional network.
• This detailed structural understanding provides insights into the self-assembly of organic molecules.
