The dinuclear iron(III) complex [Fe(salten)2(bipytz)](BPh4)2·EtOH (1) was synthesized and its post-synthesis modification yielded [Fe(salten)2(bipydz)](BPh4)2·EtOH (2). The crystal structures and magnetic behaviors of 1 and 2 were investigated by variable temperature XRD, magnetic susceptibility, and M?ssbauer spectra measurements, with each of these dinuclear iron(III) complexes exhibiting gradual spin crossover behavior.

The reaction of 3,6-di(pyridin-4-yl)-1,2,4,5-tetrazine (4-PTA) with trimesic acid (TMA) in methanol solution in a 1.5:1 mole proportion affords molecular complex 1. The structure was confirmed by single crystal X-ray diffraction study. The compound crystallizes in the triclinic space group P-1 with a = 9.7625(11), b = 11.7298(13), c = 13.0734(13), α = 68.849(10)°, β = 72.701(8)°, γ = 83.937(9)° and Z = 2. The crystal structure of 1 shows hydrogen bonding between 4-PTA and TMA, and the presence of an interstitial H2O molecule in the crystal. The zigzag 1-dimensional framework was constructed by the intermolecular hydrogen bond containing O-H...N, O-H...O and C-H...O interactions. The π-π interactions are the non-covalent forces operating between the pyridine ring in 4-PTA and benzene ring in TMA to generate 3-dimensional network.

The five new Ni(II) coordination polymers (CPs) {[Ni(bitp)(bpe)0.5(H2O)2]·0.5bpe}n (1), {[Ni(bitp)(bpa)0.5(H2O)2]·0.5bpa}n (2), {[Ni(bitp)(4,4′-bpy)0.5(H2O)]·H2O}n (3), {[Ni1.5(bitp)(Hbitp)(2,2′-bpy)(H2O)]·3H2O}n (4), and [Ni(bitp)(bipyam)]n (5), where H2bitp = 2-(benzimidazol-1-yl)terephthalic acid, bpe = 1,2-bis(4-pyridyl)ethylene, bpa = 1,2-bis(4-pyridyl)ethylane, 4,4′-bpy = 4,4′-bipyridine, 2,2′-bpy = 2,2′-bipyridine, and bipyam = 2,2′-bipyridylamine, were prepared under the same hydrothermal environments except for various N-donor ligands which can effectively regulate the structures of the complexes. For the bridging N-donor ligands bpe, bpa, and 4,4′-bpy, isostructural 1 and 2 feature three-dimensional (3D) layered-pillared frameworks with one-dimensional (1D) channels that house free bpe or bpa, while 3 is a wavelike two-dimensional (2D) stacked layer with similar 4,4′-bpy bridging auxiliary ligands. However, when terminal ligands 2,2′-bpy and bipyam are used, 2D 4 and 1D ladder chains 5 are obtained, respectively. Interestingly, 1-5 exhibit outstanding thermostability (up to 320 °C) and chemical stabilities (against boiling water, acids, bases, and organic solvents). Furthermore, on the basis of their highly thermal and chemical stability, tentative studies on the structures and properties (such as adsorption, catalysis, and magnetic properties) were undertaken. The gas sorption measurements show that 1 and 2 exhibit high adsorption selectivity of CO2 over CH4. The catalytic reactions demonstrate the role of catalysts 1-5 to synthesize 3,6-bis(pyridin-4-yl)-1,2,4,5-tetrazine. The magnetic analyses indicate that there exist a zero field splitting (ZFS) on the Ni(II) ions in 1-5.

Reaction of manganese(ii) with the electron-deficient ligand 3,6-bis(4-pyridyl)-1,2,4,5-tetrazine (pbptz) leads to distinct coordination networks whose topologies are influenced by the nature of the anions used. As anticipated, the linear ditopic ligand pbptz is involved in various types of supramolecular π interactions, i.e. π...π, lone pair...π and C-H...π interactions, which clearly play a role in the formation of the different solid-state architectures obtained, as shown by DFT calculations.
