Abstract

Reaction of nickelocene with methyllithium in the presence of diphenylacetylene at the molar ratio of reactants 1:1:2 produces a trinickel cluster with an open structure. The cluster contains a bent arrangement of nickel atoms. Two of the alkyne units are linked via a carboncarbon bond to produce a nickelacyclopentadienyl ring, while the third alkyne unit remains independently coordinated to the cluster via two π-bonds. Two Cp groups are bonded to two terminal nickel atoms. The cluster crystallizes from methylene chloride with solvent molecules in a monoclinic crystal system and P21/n space group. Corresponding unit cell parameters were determined as: a=12.4385(13) Å; b=24.994(3) Å; c=13.9657(14) Å; β=91.457(8)°; V=4340.4(8) Å3; Z=4.
