Abstract
The synthesis and characterization of novel molecular sieves containing bis(pentamethylcyclopentadienyl) cobalt(III) ion are described. Several types of molecular sieves were prepared using the cobalt metal complex as a template that was shown to be incorporated as a guest molecule within the molecular sieve. Molecular sieves prepared using bis(pentamethylcyclopentadienyl) cobalt(III) ion as template were characterized as having a pore size at least as large as 7 .ANG.. Other molecular sieves were also prepared using bis(cyclopentadienyl) cobalt(III) templates. The compounds are attractive as catalysts in a wide range of applications.
