论文摘要
One new three-dimensional polymeric PbⅡ complex, [Pb3（CTA）2（H2O）2]n·nH2O（1）,（H3 CTA = cis,cis-1,3,5-cyclohexanetricarboxylic acid）, has been synthesized. Single-crystal X-ray diffraction analyses reveal that complex 1 has a three-dimensional architecture consisting of Pb2O2 dimeric building units, which shows two types of PbⅡ centers（eight-coordinated Pb（1）,six-coordinated Pb（2） and Pb（3））. The eight-coordinated Pb（1） center possesses a stereochemically ?inactive? electron lone pair, and the coordination sphere is holodirected. However, the arrangement of oxygen atoms around Pb（2） and Pb（3） suggests a gap or hole in the coordination geometry. The stereo-chemically ?active? electron lone pairs of Pb（2） and Pb（3） possibly occupy these ?holes?, and their coordination spheres are hemidirected. Its properties have been determined by FT-IR spectra, elemental analyses and thermogravimetric analyses（TGA）. Solid-state luminescent properties of 1 also have been determined, indicating strong fluorescent emissions.
