Highly polar stacking interactions wrap inorganics in organics: lone-pair–π-hole interactions between the PdO₄ core and electron-deficient arenes

Abstract

Each PdO 4 plane of Pd 3 (OAc) 6 behaved as a 5-center nucleophile (O lone pairs and the d z 2 -Pd II orbital) that interacts with π-donating arenes to afford highly polar circular stacking, where organics wrapped inorganics.
