Synthesis and Structures of Mixed-Ligand Lead(II) Complexes with Decahydro-closo-decaborate Anion and Azheterocyclic Ligands
摘要
Abstract
Lead(II) complexation reactions were studied in the presence of salts of the closo-decaborate anion [B10H10]2– and azaheterocyclic ligands 2,2'-bipyridyl (bipy) or 1,10-phenanthroline (phen) in water and organic solvents (acetonitrile, DMF). Binuclear complex Pb(bipy)2[B10H10] and polymer complex [Pb(phen)[B10H10]] were isolated. The effect of solvents and reagent ratios on the composition and structures of the final complexes was studied. The complex compounds were identified by elemental analysis, IR spectroscopy, and X-ray powder diffraction. The structure of complex [Pb(bipy)2[B10H10]]2·2CH3CN (CCDC no. 2325841) was determined by single-crystal X-ray diffraction.
