Crystal structure and Hirshfeld surface analysis of bis(2,6-diaminopyridinium) tetrachloridocobaltate(II)

Abstract

The crystal structure of the title mol­ecular salt features N—H⋯Cl and C—H⋯Cl hydrogen bonds and π–π inter­actions; Hirshfeld surface analysis and fingerprint plots are reported.

Crystal structure, Hirshfeld surface analysis and physicochemical characterization of bis[4-(dimethylamino)pyridinium] di-μ-chlorido-bis[dichloridomercurate(II)]

“…The cations (A or B) interact via offset face-to-facestacking interactions, leading to two types of organic columns formed by the cations (A or B) with centroid-centroid distances of 3.698 (2) and 3.982 (2) Å , respectively ( Fig. 5) (Janiak, 2000;Ben Moussa et al, 2018). Similarly, the hexachloridodimercurate(II) anions are dispersed parallel to the a axis whose cohesion is ensured by ClÁ Á ÁCl [3.652 (6) Å ] and HgÁ Á ÁCl [3.167 (7) Å ] weak interactions (Sumanesh et al, 2016;Ben Moussa et al, 2019a,b;Fig.…”
