Evidence for intracrystalline chain propagation is provided by the abundance of 10-50-8, ruthenium aggregates buried within the support particle and the rare occurrence of metal particles on external surfaces (cf. Figure 2). We believe the metal aggregates observed by electron microscopy are formed by migration of ruthenium atoms to defect sites in the clay particle. These defect sites may be formed by layer folding and the formation of interfaces between discrete clay layers, as illustrated in Figure 5 . The presence of additional ruthenium, encapsulated within the galleries and too small (
