It has been characterized by IR, UV, TGA, Elemental analysis and X-ray diffraction analysis. The crystal belongs to triclinic system, P1 space group. The Crystallographic data are: a = 0.702 7(14) nm, b = 0.828 95(17) nm, c = 10.225(2) nm, α = 95.02(3)°, β = 91.45(3)°, γ = 99.85(3)°. The crystal structure data indicate that the Zn(Ⅱ) ion was coordinated with the four nitrogen atoms of two dafo and two oxygen atoms of two coordination water molecules, respectively. The complex has a one-dimensional chain structure, which is formed by hydrogen bonds.展开更多
A new compound [CoⅢ(aea)(2,2′-bipy)]Cl·H2O (aea=N-(2-aminoethyl)asp artate, 2,2′-bipy=2,2′-bipyridine) was hydrothermally synthesized and structur ally characterized, which contains a new quadridentate ligand...A new compound [CoⅢ(aea)(2,2′-bipy)]Cl·H2O (aea=N-(2-aminoethyl)asp artate, 2,2′-bipy=2,2′-bipyridine) was hydrothermally synthesized and structur ally characterized, which contains a new quadridentate ligand (aea) came from ma lic acid and ethylenediamine via in-situ reaction. The asymmetric molecules are interconnected through N-H...O hydrogen bond to form helical chains that are fur ther hold together into a two-dimensional network via the N-H...Cl hydrogen bond . The formation of aea can be considered as the substitution of hydroxyl group i n malate by ethylenediamino group, which presents a type of new in-situ ligand r eaction. CCDC: 222018.展开更多
A novel 2-D supramolecular network formed by the Fe3O building unit through three hydrogen bonds [Fe3O(O2CCH2OC6H5)6(3H2O)]NO3·2H2O (1) are presented.

The title complex crystallizes in monoclinic, space group P21/n, with a=1.709 3(2) nm, b=3.152 9(3) nm, c=1.021 2(2) nm, V=5.503 5(14) nm3, Z=4, D(calc)=1.500 g·cm-3, F(000)=2 564. Each Fe3O unit is connected by three NO3-ions and inversely each NO3-ion is surrounded by three Fe3O moieties. It shows that the well-known Fe3O unit is a potential three H-donors and may be able to be a three-connected linker. This complex displays weak anti-ferromagnetic coupling between Fe(Ⅲ) centers. Electrochemical experiments were carried out to obtain the character of its redox reaction. CCDC: 222011.展开更多
