Crystal structures of five halido gold complexes involving piperidine or pyrrolidine as ligands or (protonated) as cations.

ABSTRACT: In bromido-(pyrrolidine-κN)gold(I) bis-(pyrrolidine-κN)gold(I) bromide, [AuBr(pyr)]·[Au(pyr)₂]Br (pyr = pyrrolidine, C₄H₉N), 2, alternating [AuBr(pyr)] mol-ecules and [Au(pyr)₂]⁺ cations are connected by aurophilic contacts to form infinite chains of residues parallel to the b axis. The chains are cross-linked by three N-H⋯Br^- hydrogen bonds and an Au⋯Br contact to form a layer structure parallel to the ab plane. Tri-chlorido-(piperidine-κN)gold(III), [AuCl₃(pip)] (pip = piperidine, C₅H₁₁N), 3, consists of mol-ecules with the expected square-planar coordination at the gold atom, which are connected by an N-H⋯Cl hydrogen bond and an Au⋯Cl contac
