In the title compound, [PdCl2(C17H28N2)], the PdII atom displays a square-planar coordination involving two N atoms of a 2,6-diisopropyl-N-[(S)-pyrrolidin-2-ylmethyl]aniline ligand and two chloride ligands, with a deviation of 0.090 (1) Å for the PdII atom from the best plane. The absolute configuration of the chiral C atom of the pyrrolidine ring is S, which induces R configurations at the two N atoms of the aniline ligand. Optical isomerism arising from the chelate five-membered ring is configured as . The Pd-N bond lengths are 2.040 (3) and 2.072 (2) Å, and the Pd-Cl bond lengths are 2.3055 (8) and 2.3160 (8) Å. In the crystal, pairs of N-HCl hydrogen bonds link molecules into discrete dimers.
