Аннотация
center exhibits a distorted octa-hedral geometry with an equatorial plane formed by two bidentate picolinato ligands and axial coordination from two perchlorate anions, consistent with a Jahn-Teller distortion. The crystal structure is further consolidated by a network of hydrogen bonds involving the thia-diazole-based cations, which reside in the outer coordination sphere in a unique protonated state. Hirshfeld surface analysis reveals that O⋯H/H⋯O contacts dominate the inter-molecular inter-actions, contributing significantly to the crystal packing.
