Holodirected coordination sphere around lead(II) in three-dimensional polymeric structure; New precursor for preparation of lead oxide sulfate nano-structures
Özet
A new lead(II) three-dimensional coordination polymer, [Pb-2(mu(3)-ANS)(2)(mu(2)-Cl)(2)(H2O)(2)](n) (1) [ANS(-) = 4-amino-1 -naphthalenesulfonateb has been synthesized and characterized. The single-crystal X-ray data of compound 1 shows only one type of Pb-II ion with coordination number of six, the lead atom has distorted octahedral coordination sphere containing stereo-chemically inactive electron lone pair. The thermal stability of 1 was studied by TG-DTA (Thermo gravimetric and differential thermal analyses). Regular morphology of Pb-2(SO4)O nano-particle was prepared from fine powders of compound 1 by calcination process at 700 degrees C. This nano-structure was characterized by XRD (X-ray powder diffraction) and SEM (Scanning electron microscopy). (C) 2014 Elsevier B.V. All rights reserved.
