Synthesis and spectroscopic properties of large single-crystals of Pb(II), Hg(II) and Sr(II) methanesulfonato 1D coordination polymers

Three new 1D coordination polymers, [Pb2(CH3SO3)4(H2O)2]n, [Hg(CH3SO3)2(H2O)2]n and [Sr(CH3SO3)2(H2O)]n, were synthesized as large single crystals. The crystals were analyzed and characterized by the means of X-ray analysis, IR and NMR spectroscopy, elemental analysis and solid state UV–Vis spectroscopy. The formation of 1D polymeric chains in the crystal structures of the title compounds is affected by the various bonding modes of the bridging methanesulfonate groups. The studied compounds showed no decomposition in the air.

Three new 1D coordination polymers, [Pb2(CH3SO3)4(H2O)2]n, [Hg(CH3SO3)2(H2O)2]n and [Sr(CH3SO3)2(H2O)]n, were synthesized as large single crystals. The low price of starting materials and the facile methods used for the preparation of title compounds and their UV–Vis and broad range IR spectrums imply the studied compounds could potentially be used as optical materials.Figure optionsDownload as PowerPoint slide
