The regularities of the structural organization of crystal packings in the gold(III) iminatoamine complexes [Au(C 9 H 19 N 4 ]Y 2 (Y = I, ClO 4 , PF 6 ) and [Au(C 9 H 18 N 4 X)](ClO 4 ) 2 (X = Cl, Br) are revealed. The 3D supramolecular architecture of the crystalline lattice of the complexes is characterized by common structural units: 1D cation-anion ribbons (pseudoribbons), cation-cation stacks, and cation-anion columns that form cation-anion layers. The structures of the complexes include infinite chains of hydrogen bonds or contacts containing bridging atoms and closed rings of different dimensionality. The determining role in the topological pattern of packings of the complexes belongs to the planar character of the cation along with the presence of cis -amino groups in the AuN 4 coordination node and methyl groups in the α-position of the sixmembered delocalized ring. The halogenation of the iminate rings of the ligands does not result in a substantial change in the architecture of the packings.
