Abstract: 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 PdII cation, 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 PdN4 plane, giving a stepped conformation to the molecule. The complex displays simple intramolecular C-HN hydrogen bonds, while the unit cell consists of discrete monomeric Pd(C32H22N3)2 units which display intermolecular C-H interactions and limited intra- and intermolecular - stacking.
