摘要

Several polyoxometalate-supported metal carbonyl complexes, K7Na3P2W23O80{Re(CO)(3)}(2)center dot 38H(2)O (1), (C3H10N)(8)Na2P2W23O80{Re(CO)(3)}(2)center dot 10H(2)O (1a) and (C3H10N)(6)KNa3P2W23O80{Mn(CO)(3)}(2)center dot 7H(2)O (2), have been prepared from the dimerization of the monovacant Keggin [alpha-PW11O39](7-) with metal carbonyl complexes [M(CO)(3)](+) (M = Re, Mn) in acidic aqueous solutions. The resulting "twisted-sandwich" architectures are chiral, but their crystalline solids are racemic. A detailed investigation involving syntheses, crystal structures, and electrochemistry is presented.
