Abstract

Nucleophilic attack by the carbanion C̄H₂COCH₃ at the carbonyl atom of di-2-pyridyl ketone, (py)₂CO, in the presence of Ni^II under basic conditions has yielded the cationic cluster [Ni₄{(py)₂C(CH₂COCH₃)(O)} ₄](ClO₄)₄ (1). The cluster cation possesses a distorted cubane {Ni₄(μ₃-OR′)₄} ⁴⁺ core resulting from the η¹:η³: η¹:η¹:μ₃ coordination mode of the in situ formed ligand and has a diamagnetic ground state.
