On the Chemistry of Zn−Zn Bonds, RZn−ZnR (R = [{(2,6-Pri2C6H3)N(Me)C}2CH]): Synthesis, Structure, and Computations

Abstract
Potassium reduction of RZn(μ-I)2Li(OEt2)2 (R = [{(2,6-Pri2C6H3)N(Me)C}2CH]) affords the second compound with a Zn−Zn bond, RZn−ZnR. The air- and moisture-sensitive title compound was characterized by 1H NMR, elemental analyses, and single-crystal X-ray diffraction. The Zn−Zn bond was determined to be 2.3586(7) Å; this value is only about 0.05 Å longer than the Zn−Zn bond reported for Cp*Zn−ZnCp* (Cp* = C5Me5), the first reported compound with a Zn−Zn bond. In addition, density functional theory (DFT) computations on related model RZn−ZnR compounds provide insight into the intriguing Zn−Zn bond.
