Abstract
The preparation and X-ray characterization of a Pb2+ and a Bi3+ complex for med with macrocyclic ligands are reported. In the dimeric complex [{Pb(CH3C OO)LBPh4}(2)], where L is 1,4,7-triazacyclononane, the metal atoms are chel ated by L and bridged by an acetate group; moreover, each of the metal atom s is at contact distance from a tetraphenylborate phenyl group, which compl etes the coordination. The unsymmetrically derivatized macrocycle 1-carboxy methyl-4,7-bis(1-methylimidazol-2-ylmethyl)-1,4 HL1, in its deprotonated (L -1, anionic) form gives the complex of formula (BiClLBPh4)-B-1 with Bi3+, w hich contains [BiClL1](2)(2+) dimeric cations with eight-coodinated Bi3+ an d bridging acetate groups within the dimer.
