Abstract
Carbonylation of Na2PtCl6.6H2O, as well as K2PtCl6, in water under a CO pressure of 900 mm Hg selectively and quantitatively affords [Pt3n(CO)6n]2- (n > 6) salts. Conversely, their corresponding carbonylation at reduced CO pressure of 760-800 mm Hg leads to a convenient one-step synthesis of [Pt38(CO)44]2-.File in questo prodotto:
