parent complexes [M(‘S2C’)]2. The methyl complex [Li(4-crown-4)2][Ni(CH3)(‘S2C’)] (5) is one of the rare examples in which a methyl ligand binds to an [NiS] center. While the parent complex [Ni(‘S2C’)]2 · DMF (1) proved unreactive towards CO, 5 readily inserts CO yielding the highly reactive acetyl derivative [Ni(COCH3)(‘S2C’)]−. This complex could not be isolated, but its formation was established
