Abstract
The molecular and crystal structure of the title compound, (C8H11N4O2)2[PtCl6], synthesized from hexachloroplatinic acid and caffeine in methanol, was studied by single-crystal X-ray diffraction. The caffeinium cations form a double layer via hydrogen bonds and π-stacking interactions. The Hirshfeld surface analysis showed that the largest contribution to the crystal packing is made by H...H (31.2%), H...Cl/Cl...H (22.6%), O...H/H...O (21.9%) contacts for the cation and H...Cl/Cl...H (79.3%) contacts for the anion.
