| Popis: | The asymmetric unit of the title compound, (C6H9N2)2[CuCl4], consists of one cation and one half-anion, bisected by a twofold rotation axis through the metal center. The anion exhibits a geometry that is intermediate between a Td and D4h arrangement about the Cu atom. The crystal structure contains chains of cations alternating with stacks of anions. The cationic groups interact via offset face-to-face π–π stacking, forming chains running along the c axis. The anion stacks are parallel to the cation chains, with no significant inter- nor intrastack Cl...Cl interactions. There are several anion–cation hydrogen-bonding interactions of the (N—H)pyridine...Cl and (N—H)amino...Cl types, connecting the chains of cations to the stacks of anions. Both the N—H...Cl and π–π stacking interactions [centroid–centroid distances 3.61 (8) and 3.92 (2) Å] contribute to the formation of a three-dimensional supramolecular architecture. |
