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.

Centrosymmetric Dimers

Molecules of the title compound, C8H11NOS, are flat and almost C s-symmetric. Bond lengths and angles resemble calculated values at the B3LYP/6-311+G(2 d,p) level of theory. The solid is characterized by van der Waals bonding and π stacking (stacking distance = 3.352 Å) of the basic motif of the structure: planar centrosymmetric dimers that are bonded by pairs of symmetry-equivalent N—H...S bonds. The dimer structure is rationalized by the nature of the hydrogen-bond acceptor orbital, the S(3p) orbital located in the molecular plane. The double-donor–double-acceptor situation in the dimer results in an unusual C=S...H angle of about 127° which is large compared with isolated C=S...H bonds (circa 100°), but small compared with the almost linear acceptor geometry in related oxo compounds.
