title: Crystal structure of 8-iodo-quinolinium tetra-chlorido-aurate(III).
abstract: The structure of the title salt, (C9H7IN)[AuCl4], is comprised of planar 8-iodo-quinolinium cations (r.m.s. deviation = 0.05 Å) and square-planar tetra-chlorido-aurate(III) anions. The asymmetric unit contains one 8-iodo-quinolinium cation and two halfs of [AuCl4](-) anions, in each case with the central Au(III) atom located on an inversion center. Inter-molecular halogen-halogen contacts were found between centrosymmetric pairs of I [3.6178 (4) Å] and Cl atoms [3.1484 (11), 3.3762 (13), and 3.4935 (12) Å]. Inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonding is also found in the structure. These inter-actions lead to the formation of a three-dimensional network. Additionally, there is an intra-molecular N-H⋯I hydrogen bond between the aromatic iminium and iodine. There are no aurophilic inter-actions or short contacts between I and Au atoms, and there are no notable π-stacking inter-actions between the aromatic cations.
