Di-chlorido-(4-methyl-aniline-κN)[N-(4-methyl-phen-yl)-1-(thio-phen-2-yl)methanimine-κN]palladium(II).

Abstract

The structure of a mono-amine PdII complex, [PdCl2(C7H9N)(C12H11NS)], which crystallizes in the triclinic space group, P , is reported. The primary geometry around the PdII atom closely resembles square planar (τ4' = 0.069). In the (E)-1-(thio-phen-2-yl)-N-(p-tol-yl)methanimine ligand, the phenyl and thio-phene rings are not coplanar, subtending a dihedral angle of 38.5 (1)° because of steric effects. The PdCl2N2 coordination plane is almost perpendicular to the planes of the coordinated o-toluidine and the NC2 fragment [dihedral angles of 84.7 (1) and 72.50 (4)°, respectively]. The Pd-NH2 length of 2.040 (2) Å is slightly shorter than the observed mean value for other complexes involving a Pd atom attached to the nitro-gen of an aniline derivative. The mol-ecules display an inter-esting supra-molecular synthon based on reciprocal inter-molecular N-H⋯Cl hydrogen-bonding inter-actions of the p-toluidine amine fragment, which results in centrosymmetric dimeric units. These units are further linked by C-H⋯Cl inter-actions, resulting in chains in the c-axis direction where the mean-planes of the repeating fragment are oriented in the (110) plane.
