Iodo bridged lead(II) compounds of azoimidazoles: Single crystal X-ray structures of [di-iodo-{1-methyl-2-(p-tolylazo)imidazole}lead(II)](n) and {1-methyl-3-benzyl-2-(p-tolylazo)imidazolium}(m)-{tri-iodoplumbate(II)}(m)

摘要

PbI2 forms iodo-bridged neutral polymer upon reaction with 1-alkyl-2-(arylazo)imidazoles (RaaiR'). The reaction of PbI2 and dialkyl imidazolium iodides [RaaiR'R"]I-+(-) has synthesized {1,3-dialkyl-2-(arylazo)imidazolium}(m)-{tri-iodoplumbate(II)}(m). The complexes are characterized by different spectroscopic studies. Iodobridged chelated polymer, [Pb(RaaiR')I-2]n, has been established by single crystal X-ray diffraction measurements in one case. Tri-iodoplumbates form iodo bridged anion polymer, which connects [RaaiR'R"](+) by hydrogen bonding and are placed in between the pillars of [Pb(mu-I)(6)](n), motif. (c) 2006 Elsevier B.V.
