Novel zeotype frameworks with soft cyclodiphosphazane linkers and soft Cu₄X₄ clusters as nodes

Abstract

Two novel cyclodiphosphazane cluster frameworks with Cu4X4 clusters as tetrahedral nodes and ferrocenyl cyclodiphosphazanes [Fe(η(5)-C5H4)2(PN(t)Bu)2] as ditopic linkers have been synthesized. These frameworks having sodalite topology display a unique integration of porosity and redox activity and offer new opportunities for the synthesis of zeotype frameworks with soft phosphorus-based ligands.
