Crystal structure and Hirshfeld surface analysis of bis(2,6-diaminopyridinium) tetrachloridocobaltate(II)
In the title molecular salt, (C(5)H(8)N(3))(2)[CoCl(4)], the cations are protonated at their pyridine N atoms and the anion is an almost regular tetrahedron. The crystal structure consists of alternating inorganic layers, built from tetrachloridocobaltate anions, and organic layers formed by pro...

Sumario: | In the title molecular salt, (C(5)H(8)N(3))(2)[CoCl(4)], the cations are protonated at their pyridine N atoms and the anion is an almost regular tetrahedron. The crystal structure consists of alternating inorganic layers, built from tetrachloridocobaltate anions, and organic layers formed by protonated cations of 2,6-diaminopyridinium. The crystal packing is governed by C/N—H⋯Cl hydrogen-bonding interactions between the organic and the inorganic ions and Cl⋯Cl interactions. Moreover, the cations show a π–π stacking interaction [intercentroid distance = 3.763 (2) Å]. The prevalence of these interactions is illustrated by an analysis of the three-dimensional Hirshfeld surface and by two-dimensional fingerprint plots. |
