Naphthalene diimides, which are planar, chemically robust and redox-active, are an attractive class of electron-deficient dyes, which can undergo a single reversible one-electron reduction to form stable radical anions in the presence of electron donors upon irradiation. This makes them excellent candidates for organic linkers in the construction of photochromic coordination polymers. Such a photochromic one-dimensional linear coordination polymer has been prepared using N,N′-bis(3-carboxyphenyl)naphthalene-1,8:4,5-tetracarboximide (H2BBNDI). Crystallization of H2BBNDI with magnesium nitrate in an N,N′-dimethylformamide (DMF)/ethanol/H2O mixed-solvent system under solvothermal conditions afforded the one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-κO)magnesium(II)]-bis[μ-N-(3-carboxylatophenyl)-N′-(3-carboxylphenyl)naphthalene-1,8:4,5-tetracarboximide-κ2 O:O′]], [Mg(C28H13N2O8)2(C3H7NO)2] n . The asymmetric unit contains half of a magnesium cation, one HBBNDI− ligand and one DMF molecule. Two partially deprotonated HBBNDI− ligands bridge two magnesium cations to form a one-dimensional chain. Strong inter-chain π–π interactions between the naphthalene rings of the HBBNDI− ligand and the imide rings of adjacent chains provide a two-dimensional structure. The supramolecular three-dimensional framework is stabilized by π–π interactions between naphthalene rings of neighbouring two-dimensional supramolecular networks. The complex exhibits a reversible photochromic behaviour, which may originate from the photoinduced electron-transfer generation of radicals in the HBBNDI− ligand.

The cobalt(II) and nickel(II) cupferronato (N-nitroso-N-phenylhydroxylaminato) mixed-ligand complexes of 2-aminopyridine (2-NH2py) [Co(PhN2O2)2(2-NH2py)2] (1), [Ni(PhN2O2)2(2-NH2py)2] (2) and 2,6-diamino-4-phenyl-1,3,5-triazine (dpt) [Co(PhN2O2)2(dpt)2]·[Co(PhN2O2)2(EtOH)2] (3) have been synthesized and characterized by X-ray diffraction analysis. The cobalt (1) and nickel (2) complexes are isostructural. The crystal lattice of (3) contains different neutral cobalt(II) complexes [Co(PhN2O2)2(dpt)2] (3a) and [Co(PhN2O2)2(EtOH)2] (3b). Molecules of (1)–(3) contain octahedral metal centres with all-cis-(1) and -(2) and all-trans-(3) disposal of the ligands. Intramolecular N—H...O hydrogen bonding between the NH2 groups and the O atom of the cupferronato anion can be observed in (1)–(3). Intermolecular N—H...O and N—H...N interactions between symmetry-related molecules of (1) and (2) led to hexameric aggregates which connect through common edges into a two-dimensional supramolecular network of hexagonal-grid type. In complex (3) the self-complementary dpt units of the (3a) molecules are maintained by intermolecular N—H...N hydrogen bonds, generating infinite chains. These (3a) chains are crosslinked by the (3b) subunits via N—H...O and O—H...N hydrogen bonds, thus completing the parallel two-dimensional supramolecular network consisting of pseudo-hexagonal-grid sheets. In each crystal structure the two-dimensional supramolecular networks are controlled by both hydrogen bonds and π...π stacking interactions.

Supramolecular networks are an important subset in the field of coordination polymer (CP) frameworks and are widely encountered in crystal engineering research. The search for novel topologies continues to be a significant goal in CP chemistry. The dimeric compound bis(μ-5-carboxybenzene-1,3-dicarboxylato-κ2O1:O3)bis[(triethanolamine-κ4N,O,O′,O′′)cobalt(II)], [Co2(C9H4O6)2(C6H15NO3)2], formed from the coligands 5-carboxybenzene-1,3-dicarboxylate (tmaH2−) and triethanolamine (teaH3), namely [Co(μ2-tmaH)(teaH3)]2, was synthesized and characterized by single-crystal and powder X-ray diffraction analyses, IR spectroscopy, thermogravimetric analysis (TGA) and magnetic measurements. The crystal structure features a zero-dimensional molecular structure consisting of centrosymmetric macrocyclic dinuclear complexes. Four classical hydrogen bonds between carboxylate groups and hydroxyethyl arms stabilize and extend the molecules into a two-dimensional supramolecular network. The topological analysis indicates that an unreported (3,5)-binodal supramolecular topology with a short Schläfli symbol of (4.5.6)(4.55.63.7) can be achieved by means of intermolecular hydrogen bonds. The crystal structure accounts for the potential to obtain unique topological types from two excellent hydrogen-bonding candidates,i.e.tmaH3and teaH3. A variable-temperature magnetic study shows the existence of antiferromagnetic behaviour in the complex.
