Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(30)H(21)As·CHCl(3).
• To analyze the spatial arrangement and interactions of the naphthalene ring systems.
• To investigate the intermolecular forces governing crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of dihedral angles between naphthalene ring systems was performed.
• Identification and quantification of intermolecular interactions, including C-H⋯π and π-π stacking, were conducted.

Main Results:

• The crystal structure of C(30)H(21)As·CHCl(3) was successfully determined.
• Dihedral angles between the three naphthalene ring systems were found to be 72.54(4)°, 88.05(4)°, and 83.36(4)°.
• Molecules are arranged in stacks along the a-axis, stabilized by C-H⋯π and π-π interactions with a centroid-to-centroid distance of 3.7839(7) Å.

Conclusions:

• The crystal structure reveals a specific non-planar conformation of the naphthalene moieties.
• Intermolecular C-H⋯π and π-π interactions play a significant role in the observed crystal packing.
• This structural data provides fundamental insights into the solid-state chemistry of this organoarsenic compound.
