(Received 13 March 2013; accepted 26 March 2013; online 5 April 2013)

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.

Comment top

Palladium complexes of various types bearing the enantiopure ligands are widely used in modern asymmetric synthesis (Sodeoka et al., 2006). Palladium complexes (Quintard et al., 2008; Tan et al., 2009) containing homochiral diamine ligands derivable from natural amino acids are now well established in the clinical treatment as anticancer drugs (Barnham et al., 1994). In this paper, we describe synthesis and the crystal structure of novel chiral dichloro Pd(II) complex bearing the ligand 2,6-diisopropyl-N-(S-pyrrolidin-2-yl) methyl)benzenamine which was prepared by the reported method (Shifeng et al., 2010). The geometry around the Pd(II) centre is almost square-planar (Fig. 1). The coordination plane composed of Pd, Cl1, Cl2, N1, and N2 is nearly coplanar within 0.090 (1) Å deviation from the best plane. The bite angle of N1—Pd—N2 [84.0 (1) °] is much smaller than the Cl1—Pd—Cl2 [93.10 (3) °] angle. The chiral C atom of the pyrrolidine moiety has S configuration and the induced chiralities at two N atoms of the ligand show R configuration. The orientation of the hydrogen atoms of the chiral C and N atoms is in head-to-head. Optical isomerism arising from the chelate five-membered ring is configured as δ. The bond lengths of Pd—N are 2.040 (3) and 2.072 (2) Å and those of Pd—Cl are 2.3055 (8) and 2.3160 (8) Å. These bond lengths are similar to the known average Pd—N and Pd—Cl lengths of (1R,2R)-(1,2-bisbenzyl)-1,2- diaminocyclohexane palladium dichloride complex (Rafii et al., 2007). 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.

Experimental top

The ligand, 2,6-diisopropyl-N-(S-pyrrolidin-2-yl)methyl) benzenamine, was prepared by the reported method (Shifeng et al., 2010). Ligand (0.30 g, 1.15 mmol) solution in CH3CN (7 ml) was treated with PdCl2(CH3CN)2 (0.30 g, 1.15 mmol) in CH3CN (10 ml) at ambient temperature for overnight. The solvent was removed under reduced pressure to get brown orange reside. Washing the precipitate with cold Et2O afforded orange solid as the final product (0.38 g, 76%). Anal.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
