Bottom Line: The anion stacks are parallel to the cation chains, with no significant inter- nor intra-stack Cl⋯Cl inter-actions.There are several anion-cation hydrogen-bonding inter-actions 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 inter-actions [centroid-centroid distances 3.61 (8) and 3.92 (2) Å] contribute to the formation of a three-dimensional supra-molecular architecture.

ABSTRACT
The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[CuCl(4)], consists of one cation and one half-anion, bis-ected by a twofold rotation axis through the metal center. The anion exhibits a geometry that is inter-mediate between a T(d) and D(4h) arrangement about the Cu atom. The crystal structure contains chains of cations alternating with stacks of anions. The cationic groups inter-act 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 intra-stack Cl⋯Cl inter-actions. There are several anion-cation hydrogen-bonding inter-actions 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 inter-actions [centroid-centroid distances 3.61 (8) and 3.92 (2) Å] contribute to the formation of a three-dimensional supra-molecular architecture.
