Synthesis, crystal structure and Hirshfeld surface analysis of bis(2-amino-1,3,4-thiadiazol-3-ium) diaquadichlorido(propanedioato-κ <sup>2</sup> <i>O</i> <sup>1</sup> , <i>O</i> <sup>3</sup> )manganate(II)
In the title salt, (C<sub>2</sub>H<sub>4</sub>N<sub>3</sub>S)<sub>2</sub>[MnCl<sub>2</sub>(C<sub>3</sub>H<sub>2</sub>O<sub>4</sub>)(H<sub>2</sub>O)<sub>2</sub>], the central Mn<sup>II</sup> atom of the complex anion adopts a distorted octa-hedral coordination environment, defined by two aqua, two chlorido, and one bidentate malonato ligands. The anion is charge balanced by two thia-diazole moieties protonated at one of the heterocyclic N atoms. In the crystal, the cations and anions engage in extensive hydrogen-bonding inter-actions and short S⋯Cl contacts; additional π-π stacking inter-actions are present between adjacent cations. Hirshfeld surface analysis was used to qu-antify the inter-molecular inter-actions of the complex anion, revealing that H⋯O, H⋯Cl, and H⋯H inter-actions contribute most to the crystal packing.
