M12L8 metallo-supramolecular cube with cyclotriguaiacylene-type ligand: Spontaneous resolution of cube and its constituent host ligand

Abstract

The racemic ligand (±)-tris-(4-methylthiazolyl)cyclotriguaiacylene forms a homochiral crystalline Ag12L8 cube with spontaneous resolution. The ligand itself likewise crystallises in a chirally pure fashion in two clathrate complexes. Ag12L8 is the first example of a cyclotriguaiacylene-type coordination cube and a rare example of a M12L8-type metallo-cube.
