Treatment of [M(CO)6]– with HX (X = Cl, AcO) under anhydrpus conditions or in aqueous buffered solution yielded the diamagnetic [M2(CO)8X3]– anions of d4 niobium (I) and tantalum (I); the crystal and molecular structure of the title compound was solved by X-ray diffraction methods, showing that each niobium centre is heptaco-ordinated to four terminal carbonyl groups and to three bridging chlorides.
