Encapsulation of manganese and cobalt complexes within resorcin[4]arene dimers

Abstract

The syntheses and single-crystal X-ray structures of Mn- and Co-DMSO inclusion complexes with C-propylresorcin[4]arene dimers are reported. The Mn complex exists in one form (1), whereas the Co complex exists in two forms (2a and 2b). The hydrogen-bonded, head-to-head dimers of 1 and 2a are isostructural, with the macrocycles connected by tri-solvent bridges. The di-solvent bridged hydrogen bonds of 2b connect diagonal macrocycles.
