A New Hemi-and Holo-directed Lead(Ⅱ) Complex in Soft Ligand Environment

One new three-dimensional polymeric Pb~Ⅱ complex, [Pb_3(CTA)_2(H_2 O)_2]_n·nH_2 O(1),(H_3 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 Pb_2 O_2 dimeric building units, which shows two types of Pb~Ⅱ 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.
