The nickel (0) compound Ni(COD)(GaAr′)2 (Ar′ = C6H3-2,6-(C6H3-2,6-i-Pr 2)2), 1, was synthesized by the reaction of Ni(COD) 2 (COD = 1,5-cyclooctadiene) with (GaAr′)2. Compound 1 reacted with ethylene at 25 °C and at 1 atm pressure to give the bimetallic cluster [Ni2(GaAr′)2(η1: η1-μ2-C2H4)], 2, through the incorporation of one molecule of ethylene and displacement of COD. The structure of 2 featured an unusual Ni2Ga2C2 core bicyclic structure in which the C2H4 moiety bridges the Ga···Ga edge of a Ga2Ni2 tetrahedron. The galliums each carry an η1-bonded Ar′ substituent which complexes the nickel atom by an η6-π interaction with one of its flanking Ar' rings.
