摘要: Micro and nano-structures of a lead(II) coordination polymer, [Pb2(2-Me-8-Hq)2(MeOH)2]n (1), [2-Me-8-HqH=2-methyl-8-hydroxyquinoline], were synthesized by two sonochemical methods. These new micro characterized scanning electron microscopy, X-ray powder diffraction, IR spectroscopy elemental analyses. Compound 1 was structurally single-crystal diffraction consists primary dimeric unit [Pb2(2-Me-8-Hq)2(MeOH)2]. Self assembly between the dimmeric units [Pb2(2-Me-8-Hq)2(MeOH)2] from Pb-O bonds results in formation one-dimensional polymer. The Pb(II)-ion compound has PbO6N1 sphere with stereo-chemically 'active' lone pair on metals. By reversible solid-state structural transformation, we successfully prepared [Pb2(2-Me-8-Hq)2]n (2) thermal desolvation 1. Thermal stability studied thermo gravimetric differential In addition nano-structure PbO calcination process at 873 K.
