Abstract
Two new Cd(II) coordination polymers(CPs) [Cd2.5(L1)(Htbip)(tbip)2]n (1) and {[Cd(L2)0.5(1,4-chdc)]·H2O}n (2) (L1 = 1,2-bis(2-ethylbenzimidazol-1-ylmethyl)benzene, L2 = 1,4-bis(2-ethylbenzimidazol-1-ylmethyl)benzene, H2tbip = 5-tert-butylisophthalic acid; 1,4-H2chdc = 1,4-cyclohexanedioic acid) were hydrothermal synthesized and structural characterized. 1 can be defined as a 3D 6,8T13 network with the point symbol of {32.410.52.6}{34.412.58.64}. 2 reveals an unusual 3D xww-3,4-P21/c topological frameworks with the point symbol of {4.82.103}{4.82}. Both CPs possessed highly thermal and chemical stability. 1 and 2 can be as bifunctional luminescent sensors for effective detection of Fe3+ and norfloxacin.
