A novel 1D coordination ploymer [{Cd(hmbdc)2(2,2′-bipy)2}·H2O]n (hmbdc=5-hydroxybenzene-1,3-dioic acid) was synthesized by the hydrothermal reaction of hmbdc, CdSO4·8H2O and 2,2′-bipy. The structure was characterized by elemental analysis, IR and single crystal X-ray diffraction. The title coordination ploymer crystallized in monoclinic with space group P2/c, a=0.857 96(19) nm, b=1.113 8(3) nm, c=1.858 8(4) nm, β=104.259(9)°. The coordination polymer has an infinite chain structure and its luminescent property has also been studied. CCDC: 294519.
The Cluster compound [Cu3BrWOS3(bipy)2] was synthesized by reaction of (NH4)2WOS3, CuBr, 2,2′ bipyridine and n Bu4NBr at room temperature and characterized by IR, UV and elemental analyses. The structure of [Cu3BrWOS3(bipy)2] wasdetermined by single crystal X ray diffraction revealing that the cluster consist of a nest shaped core. The W atom is tetrahedrally coordinated by three S atoms and one O atom. There are two types of copper atoms in the WOS3Cu3 aggregate: two copper atoms are tetrahedrally coordinated and another copper atom is trigonally coordinated. The nonlinear optical properties were studied with an 8ns pulsed laser at 532nm. Its optical responses to the incident light exhibit considerably optical absorptive and strong self focusing effect with α2=0.90×10-10m·W-1, n2=2.72×10-18m2·W-1. CCDC: 196348.
The title cluster compound [WS4Cu3Br(bipy)2] has been synthesized by the reaction of (NH4)2, CuBr and 2,2′ bipy in DMF solution. 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.
