Spectral, Thermal and Structural Studies of Poly[μ-acetato(4-aminobenzoato)lead(II) monohydrate]: A Polymeric Hydrated Lead(II) Complex with Acetate Bridges

Single crystals of a lead(II) complex of 4-aminobenzoic acid, [Pb(Paba)(CH 3 COO)]·H 2 O (PabaH = 4-aminobenzoic acid) were successfully grown by gel diffusion technique using sodium metasilicate. The grown crystals were characterized by elemental analysis, fourier transform infrared (FT-IR) and UV–Vis spectroscopic techniques. The crystalline nature of the grown complex was confirmed by the powder X-ray diffraction (XRD) studies. FT-IR spectral studies were carried out to identify the functional groups. Thermal properties of the compound were studied using thermogravimetric analysis. The structure of the complex was elucidated by single crystal XRD studies. The title compound crystallizes in the centrosymmetric monoclinic space group P 2 1 / c and is having a polymeric structure. The polymeric array is constructed by the oxygen atom of acetate group and nitrogen atom of the aminobenzoate group.
