- Abstract
- Reaction of doubly negatively charged m-pyridinediyl spacered bis-bidentate ligands with iron(III) chloride in the presence of alkaline, alkaline earth, and rare earth metal cations (Mn+) yielded {2}-iron cryptates {M subset of [Fe-2(L)(3)]}(n+). The mono-, di-, and tri-valent guest cations are endohedrally encapsulated in the cavity of the bicyclic dinuclear host. In contrast, the ligands reacted with Mn2+, Co2+, and Cd2+ (M-II) cations as pentadentate tritopic chelators to give octanuclear complexes [(M8O2)-O-II(L)(6)]. Similarly, a topological equivalent pentadentate tritopic ligand L' in the presence of Zn2+ cations afforded the octanuclear cluster [Zn8O2(L')(6)]. However its reaction with iron(III) chloride and alkaline, alkaline earth, and rare earth metal cations did not lead to products of type {M subset of [Fe-2(L)(3)]}(n+).
