The Ideal

The title compound, [Pd(C11H8N)(C6H10NS2)], crystallizes with three similar and discrete molecules in the asymmetric unit. The CNS2donor set defines a distorted square-planar geometry around the PdIIatom, with very small deviations from planarity. The bidentate nature of the ligands gives fairly large deviations from the ideal 90° angles; the C—Pd—N angles are all around 81° and the S—Pd—S angles are around 75°.

The structural chemistry of the title compound, [Pd(C32H22N3)2], at 173 K is described. The compound is comprised of two deprotonated (3,5-diphenyl-1H-pyrrol-2-yl)(3,5-diphenylpyrrol-2-ylidene)amine ligands coordinated to a central PdIIcation, which lies on an inversion centre and has distorted square-planar geometry. The Pd—N bond lengths range from 2.008 (4) to 2.014 (4) Å and the bite angle is 84.16 (14)°. The chelate plane makes a dihedral angle of 45.3 (2)° with respect to the central PdN4plane, giving a stepped conformation to the molecule. The complex displays simple intramolecular C—H...N hydrogen bonds, while the unit cell consists of discrete monomeric Pd(C32H22N3)2units which display intermolecular C—H...π interactions and limited intra- and intermolecular π–π stacking.
