Thermal, spectroscopic, X-ray powder diffraction, fluorescence, and structural studies of [Pb(-4-pyc)(-Br)]n, new mixed-anion lead(II) 3-D coordination polymers

A new Pb(II) 3-D coordination polymer, [Pb(-4-pyc)(-Br)]n (1) {4-Hpyc = 4-pyridinecarboxylic acid}, has been synthesized and characterized by elemental analysis, IR spectroscopy, and structure determined by single-crystal X-ray diffraction. The crystal structure consists of 3-D polymeric units. The thermal stability of 1 was studied by thermal gravimetric and differential thermal analyses.
