Sažetak
Air oxidized methanol or methanol-water alkaline (pH> 10)
solutions of [Ta6Cl12] Cl2 · 8H20 were used for the preparation of
cluster hydroxides of the composition, M2 [Ta6Cl!2] (OH)6 · nH20
with M == Na, K, Rb, (CHa)4N+ and (C2H5)4N+. These crystalline,
water-soluble compounds exhibit magnetic and spectral properties
confirming the +4 cluster unit.
Aspects of air oxidation of the cluster unit in alkaline medium
are discussed. The insoluble cluster hydroxide, [Ta6Ch2] (0H)4 ·
· lOH20 and soluble halide clusters, [Ta6Cl12] X4 · nH20 and
[Ta0Ch2l Xo2-, X == Cl, Br, are the products of reactions with
acids. There is no evidence for entry of the OH- ions into the
inside coordination sphere of the cluster unit.
