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.

In the binuclear title compound, [Ag2(C11H11N3)2](ClO4)2·2C2H6SO, the complex cation is centrosymmetric, with the unique AgIcation coordinated by two pyridine N atoms from two symmetry-relatedN-(pyridine-2-ylmethyl)pyridine-3-amine ligands in a geometry slightly distorted from linear [N—Ag—N = 170.78 (9)°], resulting in the formation of a 16-membered cyclic dimer. The two pyridine rings coordinating to the AgIatom are almost perpendicular to each other [dihedral angle = 87.73 (10)°]. Intermolecular Ag...O interactions [3.149 (3) and 2.686 (3) Å], N—H...O and C—H...O hydrogen bonds and C—H...π interactions between the cyclic dimers and the anions or the solvent molecules lead to the formation of a three-dimensional supramolecular network.

The title compound, C10H5ClF2N2OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2 (2)° and the equalization of the amide C—N bond lengths reveals the existence of conjugation between the benzene ring and the thiazole unit. In the crystal, pairs of N—H...N hydrogen bonds link molecules into inversion dimers. Non-classical C—H...F and C—H...O hydrogen bonds stabilize the crystal structure.
