Two nickel(Ⅱ) and zinc(Ⅱ) coordination polymers, namely {[Ni(μ₃-cpna)(μ-dpea)_0.5]·H₂O}_n (1) and {[Zn(μ₃-cpna)(μ-dpey)_0.5]·H₂O}_n (2) have been constructed hydrothermally using 5-(2-carboxyphenyl)nicotinic acid (H₂cpna), 1, 2-di(4-pyridyl)ethane (dpea), 1, 2-di(4-pyridyl)ethylene (dpey), and nickel and zinc chlorides at 160℃. The products were isolated as stable crystalline solids and were characterized by IR spectra, elemental analyses, thermogravimetric analyses, and single-crystal X-ray diffraction analyses. Single-crystal X-ray diffraction analyses revealed that two compounds crystallize in the monoclinic or orthorhombic systems, space groups, P2₁/c or Pbca. Both compounds show 3D metal-organic frameworks. Compound 2 exhibited an effective catalytic activity in the Knoevenagel condensation reaction at room temperature. Meanwhile, compound 2 showed an effective anti-wear performance in poly-α-olefine synthetic lubricant.

The adsorption behaviors of intrinsic graphene-like GaN (g-GaN) and transition metal (TM) atom-doped g-GaN on Cl₂ and CO gas molecules were systematically investigated using first-principles calculations based on density functional theory. The results show that the adsorption of both Cl₂ and CO on the intrinsic g-GaN was physisorbed, and since the adsorption energies of both systems were positive, it indicates that the systems are unstable. On the contrary, the adsorption energies of Cl₂ and CO upon adsorption on Fe- and Co-doped g-GaN were negative and small, and the adsorption system is stable. By analyzing the properties of the density of states, charge density difference, and energy band structure, it can be concluded that the introduction of transition metal atoms can effectively enhance the interaction between gas molecules and g-GaN.

Three zinc(Ⅱ), nickel(Ⅱ), and cadmium(Ⅱ) complexes, namely [Zn(μ-Htpta)(py)₂]_n (1), [Ni(H₂biim)₂(H₂O)₂][Ni(tpta)(H₂biim)₂(H₂O)]₂·3H₂O (2), and [Cd₃(μ₄-tpta)₂(μ-dpe)₃]_n (3), have been constructed hydrothermally at 160 ℃ using H₃tpta ([1, 1′: 3′, 1″-terphenyl]-4, 4′, 5′-tricarboxylic acid), py (pyridine), H₂biim (2, 2′-biimidazole), dpe (1, 2-di (4-pyridyl)ethylene), and zinc, nickel and cadmium chlorides, resulting in the formation of stable crystalline solids which were subsequently analyzed using infrared spectroscopy, element analysis, thermogravimetric analysis, as well as structural analyses conducted via single-crystal X-ray diffraction. The findings from these single-crystal X-ray diffraction studies indicate that complexes 1-3 form crystals within the monoclinic system P2₁/c space group (1) or triclinic system P1 space group (2 and 3), and possess 1D, 0D, and 3D structures, respectively. Complex 1 demonstrated substantial catalytic efficiency and excellent reusability as a heterogeneous catalyst in the reaction of Knoevenagel condensation under ambient temperature conditions. In addition, complex 1 also showcased notable anti-wear performance when used in polyalphaolefin synthetic lubricants.
