Abstract

Herein, we report a twisted cubic Cu(I)₄Ti(IV)₄-oxo cluster stabilized by in situ – formed 2,2′-biphenolate ligands from the oxidative coupling of phenols. The 2,2′-biphenolate-functionalized Cu(I)₄Ti(IV)₄O₄ cluster shows short Cu⋯C contacts and exhibits smaller HOMO–LUMO gaps than those of reported Ti(IV)₄O₄.
