Abstract

Molecular halide clusters, [(M6Cl12)Cl2(H2O)4]⋅4H2O (M = Nb, Ta) and (H3O)2[(M6Cl8)Cl6]⋅6H2O (M = Mo, W), develop catalytic activity for the dehydration of alcohols to yield olefins and ethers when they are treated at 300 °C. The activity of the W cluster appears at 250 °C at which temperature it changes to the poorly crystallized three-dimensional linked cluster [W6Cli 8]Cla 4Cla-a 4/2, and decreases at 400 °C at which temperature the crystallinity improves.
