The crystal is of monoclinic, space group P2 1/n with a = 5.5079(5), b = 15.0973, c = 9.9825(9) A, β = 90.2380(10)°, C14H16N4NiO6, Mr = 395.02, Z = 2, V = 830.08(13) A^3 Dc = 1.580 g/cm^3, μ(MoKa) = 1.208 mm^-1, F(000) = 408, R = 0.0234 and wR = 0.0603 for 1379 observed reflections (I 〉 2σ(I)). In the title complex, adjacent nickel(Ⅱ) ions are bridged through the oxygen atoms of carboxylic groups in syn-anti conformation, yielding an infinite one-dimensional chain.

Single crystal X-ray diffraction analysis reveals that the complex crystallizes in the monoclinic space group P2 1/n with a=0.84823(3), b=0.91440(3), c=1.65141(2) nm, β=91.243(2)°, V=1.28057(6) nm 3, Z=4. The coordination geometry at each Zn(II) center is a distorted tetrahedron. Two independent bdc ligands in a herringbone pattern link alternatively four-coordinated Zn(II) centers into a one-dimensional polymeric chain. Hydrogen bonds among coordinated water molecules and uncoordinated oxygen atoms of two independent bdc ligands from different polymeric chains extend one-dimensional polymeric chains into a three-dimensional structure.展开更多

Attributes of substantial porosity, specificsurface area, exposed metal centers, uniform structure, and flexible morphology render PET-derived MOFs are well-suited for applications inadsorption, energy storage, catalysis, among others. Herein, in the present work, we have summarized recent advances in synthesis of PETderived MOFs using ex-situ and in-situ methods for typical applications of adsorption, catalysis and energy storage. Despite those improvementsin synthesis methods and potential applications, challenges still remain in development of green and economical routes to fully utilize waste PETfor massive manufacture of valuable MOF materials and chemicals. This review provides insights into the conversion of non-degradable PETwaste to value-added MOF materials, and further suggests promising perspectives to develop the sustainable “Waste-to-MOFs” model inaddressing environmental pollution and energy crises.展开更多

Compound 1 crystallizes in orthorhombic, space group Pca21 with a = 21.487(6), b = 7.790(2), c = 20.666(6) A, C30H40Cd2N2O11, Mr = 829.44, V= 3459.3(16) A3, Z = 4, Dc = 1.593 g.cm-3,μ = 1.29 mm-1, F(000) = 1672, 2.7〈θ〈27.2°, λ(MoKa) = 0.71073 A, T= 293(2) K, the final R = 0.026, wR = 0.0548 and S = 1.027. X-ray diffraction analysis reveals that complex 1 possesses a 3D framework and exhibits rnsw net. Thus, the solid-state luminescent spectrum of 1 displays that the emission of cadmium(lI) complex shows a peak at 317 nm upon 250 nm excitation at room temperature.展开更多
