A novel homochiral holodirected coordination polymer of lead(II) nitrate with the bridging ligand 1,2-bis(4-pyfidyl)ethane (bpa), [Pb-2(mu-bpa)(3)(mu-NO3)(2)(NO3)(2)](n) (1), has been synthesized and characterized by elemental analysis, FT-IR, thermal analysis and single crystal X-ray diffraction. In 1, the lead(II) ions are doubly bridged by both bpa and nitrate ligands into a chiral infinite three-dimensional polymeric network. There are two different nine- and eight-coordinate geometries around the lead(II) ion in 1, in which the lead(H) ions have a less common holodirected geometry. Solid-state luminescent spectra of compound 1 indicate intense fluorescent emission at ca. 434 nm. (C) 2007 Elsevier Masson SAS. All rights reserved.
