Anomalous Behaviour of - and - towards Protons. Crystal and Molecular Structure of the Organometallic Acid +-*C4H8O

Treatment of - with HX (X = Cl, AcO) under anhydrous conditions or in aqueous buffered solution yielded the diamagnetic - anions of d4 niobium(I) and tantalum(I); the crystal and molecular structure of the title compound was

New Carbonyl Derivates of Niobium(I) and Tantalum(I)

The hexacarbonylmetalates(1-) of niobium and tantalum are oxidised by H+ and halogens to give the - anions (X = Cl, Br, I).By exchange reactions, the ν-acetato- and ν-methoxocomplexes (X = O2CMe or OMe) were also obtained.The crystal and molecular structure of was investigated by X-ray diffraction methods.Crytals are triclinic, space group P1, with a = 16.283(3), b = 9.293(2), c = 9.050(2) Angstroem, α = 113.01(2), β = 96.56(2), γ = 98.39(2) deg, U = 1224.7 Angstroem3, Dc = 1.792 g cm-3 (Z = 2), ν(Mo-Kα) = 12.2cm-1.The two niobium atoms of the dimeric anion are bridged by three chlorides located at the vertices of an approximately equilateral triangle perpendicular to the niobium-niobium vector .The seven-co-ordination of niobium is completed by four carbonyl groups.The dimeric chloride-bridged complexes of niobium(I) and tantalum(I) undergo the following reactions: (a) reduction by sodidum to the hexacarbonylmetalate(1-); (b) chloride substitution by C5H5- to the cyclopentadienyl derivates 5-C5H5)(CO)4> in good yields and by arenes in the presence of aluminium bromide to the new cationic complexes 6-arene)(CO)4>+ as their hexa(bromo)chlorodialuminate derivates.
