title: Crystal structure of 2,2'-bi-pyridine-1,1'-diium tetra-chlorido-zincate.
abstract: In the crystal structure of the title salt, (C10H10N2)[ZnCl4], the bi-pyridine-diium dication is not planar, with a dihedral angle of 37.21 (9)° between the planes of the two pyridine rings. In the crystal, the slightly distorted [ZnCl4](2-) anions are packed into rods parallel to [001], with the organic cations arranged in corrugated layers parallel to (100). Cations and anions are linked through N-H⋯Cl hydrogen bonds, forming chains parallel to [20-1]. Additional C-H⋯Cl inter-actions consolidate the crystal packing.
