An encapsulated oxo-bridged organometallic cluster catalyst and a process for the preparation thereof by interacting a zeolite HY with a mixture of solutions of sources of transition metal ions at a temperature in the range of 298 K to 358 K under constant stirring to obtain a solid product, washing and drying the solid product thoroughly at 390 to 410 K, and then adding to it a mixture of an acid, pyridine, salt of alkali metal and water, under constant agitation and in a dynamic aerobic environment for 2 to 4 hours at 298 K and separating and drying the encapsulated complex at 298 K under vacuum to obtain the desired encapsulated oxo-bridged organometallic cluster catalyst.
