Abstract (EN): The Keggin-type TBA(4)H(2)[BW11Mn(H2O)O-39]center dot H2O (BW11Mn) compound was isolated and characterized. The first sphere of coordination for the manganese atom was determined by EXAFS analysis. Six oxygen atoms were found in the range of 1.80-2.64 angstrom from the manganese. BW11Mn showed to be an active, efficient and selective catalyst for cis-cyclooctene (la) epoxidation in the presence of stoichiometric quantities of H2O2. After 5 h of reaction almost complete conversion was achieved (86% of conversion). Selectivity was always 100 % for the epoxide.
