Abstract
Treatment of [M(CO)J - with HX (X = CI, AcO) under anhydrous conditions or in aqueous buffered solution yielded the diamagnetic [M2(C0)8X3-] anions of d4 niobium([) and tantalum(!); 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.File in questo prodotto:
