Integrative Assembly of Heteroleptic Tetrahedra Controlled by Backbone Steric Bulk.

ABSTRACT: A bent fluorenone-based dipyridyl ligand L^A reacts with Pd^II cations to a solvent-dependent dynamic library of [Pd_nL_2n] assemblies, constituted by a [Pd₃L^A₆] ring and a [Pd₄L^A₈] tetrahedron as major components, and a [Pd₆L^A₁₂] octahedron as minor component. Introduction of backbone steric hindrance in ligand L^B allows exclusive formation of the [Pd₆L^B₁₂] octahedron. Combining equimolar amounts of both ligands results in integrative self-sorting to give an unprecedented [Pd₄L^A₄L^B₄] heteroleptic tetrahedron. Key to the non-statistical assem
