| Abstract: | 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′)I2]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(μ-I)6]n motif. |
