The title compound [2-dapp]2[Zn(dmit)2] synthesized by the direct reaction of [Et4N]2[Zn(dmit)2] and [2-dapp]I crystallizes in monoclinic, space group P2l/c with a = 29.7436(6), b = l0.6266(3), c = l3.6161(4) ? b = 93.l16(l)? V = 4297.3 ?, Z = 4, Dc = 1.448 g/cm3, m = 1.091 mm-1 and F(000) = 1936. The structure was refined by fu1l-matrix 1east-squares methods to the final R = 0.075 and wR = 0.l16, revealing the zinc-bis (dmit) anions interact strongly with the planar cation, 2-dapp+, by the hydrogen bond C(l)H(lC)…S(7) (x, 3/2y, 1/2+z).
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.
