The title cyclometalated platinum(II) complex with 2-(4-bromophenyl)pyridinato and acetylacetonato ligands, [Pt(C11H7BrN)(C5H7O2)], consists of two crystallographically non-equivalent dimers, each stacked by π–π interactions with distances of ≃ 3.4 Å. In both dimers, the platinum(II) complexes are arranged antiparallel to each other. Each complex exhibits a slightly distorted square-planar coordination environment around the central Pt(II) atom. The dihedral angles between two chelate rings including the PtIIatom in these complexes are 0.08 (12) and 1.54 (9)°.

Reaction of copper(II) nitrate with pivaloylhydroxamic acid yielded the title compound, [Cu(pivHA)2] (where pivHA− is pivaloyl hydroxamate, C5H10NO2). The centrosymmetric mononuclear complex consists of a CuII ion, which is located on a center of inversion, with two coordinated pivaloyl hydroxamate monoanions. The CuII ion has a square-planar coordination environment consisting of four O atoms – two carbonyl O atoms and two hydroxamate O atoms from two hydroxamate pivHA− ligands. The pivHA− anions are coordinated to copper(II) in a trans-mode, forming two five-membered O,O′-chelate rings.

The asymmetric unit of the title compound, C56H50N6O8S2·3C6H4Cl2, contains two half-molecules of the parent,AandB, which both have crystallographic inversion symmetry, together with three 2,3-dichlorobenzene molecules of solvation. MoleculesAandBare conformationally similar, with dihedral angles between the central naphthalenediimide ring and the peripheral naphthalene and benzyl rings of 2.43 (7), 81.87 (7)° (A) and 3.95 (7), 84.88 (7)° (B), respectively. The conformations are stabilized by the presence of intramolecular π–π interactions between the naphthalene ring and the six-membered diimide ring of the central naphthalenediimide moiety, with ring centroid-to-centroid distances of 3.5795 (8) Å (A) and 3.5640 (8) Å (B). In the crystal, C—H...O hydrogen bonds link the molecules into infinite supramolecular chains along thecaxis. These chains are interconnected through C—H...π and offset π–π interactions, generating supramolecular nanotubes which are filled by 1,2-dichlorobenzene molecules.

Both PdIIatoms have a slightly distorted square-planar coordination environment. Weak intermolecular contacts of the type C—H...Pd seem to have a significant influence on the arrangement of the molecules along thebaxis in the crystal.

In the title compound, C19H13ClF2N2O2, the conformation of the N—H bond in the amide segment isantito the C=O bond. The molecule is not planar, with dihedral angles between the central benzene ring and the outer benzene and pyridyl rings of 73.35 (7) and 81.26 (6)°, respectively. A weak intramolecular C—H...O hydrogen bond occurs. In the crystal, N—H...N, C—H...O and C—H...F hydrogen bonds lead to the formation of dimers. The N—H...N inversion dimers are linked by π–π contacts between adjacent pyridine rings [centroid–centroid = 3.8541 (12) Å] and C—H...π interactions. These contacts combine to stack the molecules along theaaxis.

The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two CuIIatoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu—O contacts, yielding an overall square-pyramidal coordination environment for each of the four CuIIatoms. The molecules are arranged in layers parallel to (101). Non-classical C—H...O hydrogen-bonding interactions are observed between the layers.

The title compound, (C12H12BrN2)[Ni(C4N2S2)2], is an ion-pair complex, isostructural with the Cl-containing analogue. The anion lies on an inversion centre and the NiII ion is coordinated by four S atoms, giving the expected square-planar coordination geometry. The cation adopts a conformation where the benzene and pyrazine rings are twisted with respect to the plane of the central C—C—N chain which links them. C—H...S and π–π interactions between cations and anions are observed in the crystal structure, and C—H...π interactions mediate the formation of ribbons of cations.
