Abstract

The reaction of Pb [BF4] 2 in H2O/MeCN solution with the macrocycle 18-crown-6 gave the dinuclear complex [{Pb (18-crown-6)(H2O)(μ2-BF4)} 2][BF4] 2, containing two nine- coordinate lead centres, each bound to all six oxygens of a crown ligand, one water molecule and bridged by two μ2-BF4 groups. In contrast, the oxa-thia crown [18] aneO4S2 gave the mononuclear [Pb ([18] aneO4S2)(H2O) 2 (BF4)][BF4] in which the lead is ...
