Purpose of the Study:

• To elucidate the crystal structure of the [Ag(C12H8N2S)2]ClO4 salt.
• To analyze the coordination environment around the silver(I) ion.
• To determine the structural characteristics of the thienylquinoxaline ligand within the complex.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed.
• The crystal structure was solved and refined.
• Symmetry elements and molecular geometry were analyzed.

Main Results:

• The crystal structure of [Ag(C12H8N2S)2]ClO4 was determined, revealing C2/c symmetry.
• The silver(I) atom and the perchlorate anion reside on a twofold rotation axis.
• The perchlorate anion displays disorder around this axis.
• The thienylquinoxaline ligand is nearly planar, with a small dihedral angle between the thienyl and quinoxaline rings (10.88(8)°).

Conclusions:

• The crystal structure provides insights into the coordination behavior of silver(I) with thienylquinoxaline ligands.
• The observed symmetry and ligand planarity influence the overall crystal packing.
• This structural information is fundamental for further studies on the properties and applications of such silver complexes.
