Bis[2-phenyl-1-(phenyliminio)isoindoline] di-μ-chlorido-bis[dichloridopalladate(II)] benzene disolvate

J. M. Chitanda, J. W. Quail and S. R. Foley

In the title compound, (C₂₀H₁₇N₂)₂[Pd₂Cl₆]·2C₆H₆, the dichloride-bridged [Pd₂Cl₆]²⁻ anion lies across an inversion center with each Pd^II ion in a slightly distorted square-planar environment. In the crystal structure, two cations and an anion are connected via N—H

Cl hydrogen bonds between the NH groups of the iminioisoindoline cations and terminal Cl atoms of a hexachloridodipalladate(II) anion. The Pd—Cl distance of the terminal chloride engaged in hydrogen bonding is slightly longer than the Pd—Cl distance of the adjacent terminal chloride which is not involved in hydrogen bonding.

Comment top

As part of the ongoing research in our laboratory directed at the synthesis of substituted palladacycles incorporating iminoisoindolines (Chitanda et al., 2008), the title compound, I, was obtained by reaction of 1-phenylimino-2-phenylisoindoline with dichloropalladium(II) in the presence of HCl. The bis-iminoisoindolinium hexachlorodipalladate complex crystallizes with two molecules of benzene in the unit cell of the triclinic space group P1. The crystal structure of I is stabilized by a system of intermolecular hydrogen bonds between the imine NH atoms of the iminoisoindolinium cation and the termininal chloride atoms in the hexachlorodipalladate(II) anion. The Pd₂Cl₆^2- anion lies across an inversion center and has the expected planar dichloro-bridged structure with the Pd—Cl distance of the terminal chloride engaged in hydrogen bonding being slightly longer at 2.2929 (7)Å than the Pd—Cl distance of the adjacent terminal chloride at 2.2635 (7)Å which does not show any H-bonding. In previously reported structures incorporating a Pd₂Cl₆^2- anion, the anion most often lies across an inversion center (Bartczak et al., 2001; Fábry et al., 2004; Lassahn et al., 2003; Ojwach et al., 2007; Schupp et al., 2001; Yang et al., 2008). The molecular structure and packing of the title compound is shown in Figs. 1 and 2.

The title compound was synthesized by reaction of 1-phenylimino-2- phenylisoindoline with dichloropalladium(II) in the presence of HCl in dichloromethane. Single crystals were obtained by slow evaporation from a benzene solution at ambient temperature.

Special details top

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.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
