A Zinc–Zinc‐Bonded Compound and Its Derivatives Bridged by One or Two Hydrogen Atoms: A New Type of ZnZn Bonding

Abstract

Unique interactions: Ar′ZnZnAr′ (1; Ar′=C6H3-2,6-(C6H3-2,6-iPr2)2), the dimer Ar′Zn(μ-H)2ZnAr′ (2), and the unprecedented species Ar′Zn(μ-H)(μ-Na)ZnAr′ (3) were synthesized and fully characterized. DFT calculations show that the ZnZn bonding interactions in 1 differ from those of other ZnZn compounds, and the calculations also indicate a new type of ZnZn bond in 3.
