Exploiting host-guest chemistry to manipulate magnetic interactions in metallosupramolecular M₄L₆ tetrahedral cages.

ABSTRACT: Reaction of Ni(OTf)₂ with the bisbidentate quaterpyridine ligand L results in the self-assembly of a tetrahedral, paramagnetic cage [Ni^II ₄ L ₆]⁸⁺. By selectively exchanging the bound triflate from [OTf⊂Ni^II ₄ L ₆](OTf)₇ (1), we have been able to prepare a series of host-guest complexes that feature an encapsulated paramagnetic tetrahalometallate ion inside this paramagnetic host giving [M^IIX₄⊂Ni^II ₄ L ₆](OTf)₆, where M^IIX₄ ^2- = MnCl₄ ^2- (2), CoCl₄ ^2- (5), CoBr₄ ^2- (6), NiCl<
