Dichlorido{2,6-diisopropyl-N-[(S)-pyrrolidin-2-ylmethyl]aniline-κ2 N,N′}palladium(II)

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 δ. 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—H⋯Cl hydrogen bonds link molecules into discrete dimers.

In the crystal, pairs of N-HÁ Á ÁCl hydrogen bonds link molecules into discrete dimers.
There are two intermolecular N-H···Cl between each two molecules to form discrete dimers as shown in Fig. 2.
Hydrogen-bond parameters are listed in Table 1.

Refinement
All H atoms were positioned geometrically and refined using a riding model with C-H 0.93 -0.98 Å, N-H 0.86 Å and U iso = 1.5U eq (C) for CH 3 and 1.2U eq (C,N).
