Abstract: | A new lead diphosphonate, Pb2(O3PCH2C6H4CH2PO3) was hydrothermally synthesized from tetraethyl α,α′-p-xylenediphos-phonate and Pb(NO3)2. The structure was solved and refined using X-ray powder diffraction data. It crystallizes in the monoclinic space group P21/c, with a = 467.84(2), b = 2007.98(9), c = 639.10(2) pm, β = 101.020(3)°, V = 589.31(4) 106 pm, Z=2, wRp=0.034, Rp=0.027, RF2=0.061, RF=0.036. The structure is built from corner-linked [PbO4] polyhedra, containing a lone pair of electrons. These polyhedra are connected to layers by phosphonate groups, RPO32− and through the organic diphosphonic acid to a three-dimensional structure. Thermogravimetric as well as IR spectroscopic studies are also presented. |
