Motion of an isolated water molecule within a flexible coordination cage: structural properties and catalytic effects of ionic palladium(II) complexes

Abstract

The unique cage complexes [[(Me(4)en)Pd](3)(L)(2)](X)(6) (L = 1,3,5-tris(isonicotinoyloxyethyl)cyanurate; X(-) = BF(4)(-), ClO(4)(-)) were constructed. A single water molecule in a skeletal cage was reversibly associated and dissociated via a combination of the adequate space, polar environment, and conformational flexibility of the cage. In Suzuki-Miyaura C-C cross-coupling reactions, the cage complex showed significant catalytic activity along with the effects of the isolated single water molecule.
