摘要

The reaction of bis(cyclooctadiene)nickel with Ga₄[C(SiMe₃)₃]₄ (1) yields a coordination compound analogous to [Ni(CO)₄], [Ni{Ga-C(SiMe₃)₃}₄], which shows a tetrahedral coordination of the central nickel atom, linear Ni-Ga-C groups, and very short Ni-Ga distances. Quantum-chemical DFT calculations on the model complexes [Ni(EMe)₄] (E = B, Al, Ga, In, Tl) verify strong π back-donation of electron density from nickel to the empty p(π) orbitals of the group 13 elements, which is more effective than in tetracarbonylnickel itself.
