Two noble metal complexes involving ancillary chloride ligands and chelating 2,2′‐bipyridylamine (Hdpa) or its deprotonated derivative (dpa), namely [bis(pyridin‐2‐yl‐κ N )amine]tetrachloridoplatinum(IV), [PtCl 4 (C 10 H 9 N 3 )], and [bis(pyridin‐2‐yl‐κ N )aminido]dichloridogold(III), [AuCl 2 (C 10 H 8 N 3 )], are presented and structurally characterized. The metal atom in the former has a slightly distorted octahedral coordination environment, formed by four chloride ligands and two pyridyl N atoms of Hdpa, while the metal atom in the latter has a slightly distorted square‐planar coordination environment, formed by two chloride ligands and two pyridyl N atoms of dpa. The difference in conjugation between the pyridine rings in normal and deprotonated 2,2′‐dipyridylamine is discussed on the basis of the structural features of these complexes. The influence of weak interactions on the supramolecular structures of the complexes, providing one‐dimensional chains of [PtCl 4 (C 10 H 9 N 3 )] and dimers of [AuCl 2 (C 10 H 8 N 3 )], are discussed.
