Abstract
The clustering of cobalt in CoAPO-5 is studied by means of quantitativ e P-31 MAS NMR. To explain the amount of ''NMR-invisible'' P as functi on of the cobalt content, clusters consisting of at least five cobalt atoms have to be present inside the framework. Probably, cobalt atoms belonging to one cluster are situated in the wall of one and the same pore. (C) 1997 Elsevier Science B.V.
