Abstract: In the title complex, [Pd(C11H9N2)2], the PdII atom is located on an inversion centre and has a square-planar coordination geometry. The phenyl substituents at the imine N atoms make a dihedral angle of 75.0 (6)° with respect to the PdN4 plane.

In the title compound, [Ni(C₁₂H₁₁N₂)₂], the NiII cation lies on an inversion centre and has a square-planar coordination geometry. This transition metal complex is composed of two deprotonated N,N'-bidentate 2-[(phenylimino)ethyl]-1H-pyrrol-1-ide ligands around a central NiII cation, with the pyrrolide rings and imine groups lying trans to each other. The Ni-N bond lengths range from 1.894 (3) to 1.939 (2) Å and the bite angle is 83.13 (11)°. The Ni-N(pyrrolide) bond is substantially shorter than the Ni-N(imino) bond. The planes of the phenyl rings make a dihedral angle of 78.79 (9)° with respect to the central NiN₄ plane. The molecules are linked into simple chains by an intermolecular C-H∙∙∙π interaction involving a phenyl β-C atom as donor. Intramolecular C-H∙∙∙π interactions are also present.

Nitrogen-based polydentate ligands are of interest owing to their flexible complexation to transition metal atoms. For the title compound, [Ni(C15H17N2)2], a transition metal complex formed by the coordination of two identical N,N'-bidentate mono(imino)pyrrolyl ligands to an Ni(II) centre, an X-ray crystal diffraction study indicates that the two ligands show an inverted arrangement with respect to one another around the Ni(II) centre, which is located on a crystallographic inversion centre. The planes of the aromatic substituents at the imine N atoms of the ligands show dihedral angles of 85.91 (5)° with respect to the NiN4 plane. The Ni-N bond lengths are in the range 1.9072 (15)-1.9330 (15) Å and the Nimino-Ni-Npyrrole bite angles are 83.18 (6)°. The Ni-Npyrrole bond is substantially shorter than the Ni-Nimino bond. Molecules are linked into an extensive network by means of intermolecular C-H...π(arene) hydrogen bonds in which every molecule acts both as hydrogen-bond donor and acceptor. The supramolecular assembly takes the form of an infinite two-dimensional sheet.
