By coordination of the ligand with CdI2, a complex CdI2 L2 was obtained. The structure of the complex was analyzed through single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 25.277(5), b = 11.176(5), c = 17.912(5) ?, β = 106.056(5)°, V = 4863(3) ?3, Z = 4, Dc =1.633 Mg/m3, F(000) = 2360, Μr = 1195.19, μ = 1.766 mm-1, the final R = 0.0323 and wR = 0.0758 for 33414 observed reflections with I > 2?(I). The linear absorption spectra of the complex were experimentally and theoretically studied. And the third-order nonlinear optical(NLO) property of the complex was also measured through Z-scan technique.展开更多

The crystal is of triclinic, space group PI with a = 8.823（3）, b = 18.799（7）, c =23.065（9） A, α = 77.349（6）, β = 83.128（7）, ）, γ= 80.942（3）°, V = 3671.5（12） A^3, Z = 1, Dc = 1.266 g/cm^3,/z = 0.361 mm^-1 F（000） = 1482, the final R = 0.0587 and wR = 0.1284 for 6562 observed reflections with I 〉 2σ（I）. In the molecular structure of （COCl2L4）2, there are two crystallographically unique units. The Co^Ⅱ atoms are six-coordinated by four N atoms from four imidazole ligands （L） and two Cl atoms to form a distorted octahedral geometry. The optical properties of complex （COCl2L4）2 have been experimentally studied.展开更多

Single crystal X ray diffraction data show that the compound has a nest shaped structure. Nonlinear optical properties (NLO) of the cluster were investigated by a Z scan technique with a pulsed laser at 532nm. The cluster exhibits the strong NLO absorption and a self defocusing effect (effective non linear absorption coefficient, α2eff=7.3×10-11mW-1; effective non linear refractive index, n2eff=3.9×10-11esu) when measured in a 6.0×10-4mol·dm-3 DMF solution.
