Abstract

A compound containing fullerene dimers bonded through two nickel atoms, {Ni(Ph₃P)}₂(μ₂–η²,η²-C₆₀)₂·2C₆H₄Cl₂ (1), has been obtained as single crystals. The fullerenes are neutral in 1 , showing a zero-valent state of Ni. The nickel atoms are bonded in an η² coordination mode with Ni–C distances of 2.001(3)–2.037(3) Å and a close approach of the fullerenes with a 9.716 Å center-to-center distance. The DFT calculations showed a diamagnetic singlet ground state for this dimer.
