The structural chemistry of the title compound, [Pd(C 32 H 22 N 3 ) 2 ], at 173 K is described. The compound is comprised of two deprotonated (3,5‐diphenyl‐1 H ‐pyrrol‐2‐yl)(3,5‐diphenylpyrrol‐2‐ylidene)amine ligands coordinated to a central Pd II 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 PdN 4 plane, 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(C 32 H 22 N 3 ) 2 units which display intermolecular C—H...π interactions and limited intra‐ and intermolecular π–π stacking.
