The present invention provides a liquid organomagnesium precursor having formula Mg(OR')X}.aMgX2}.bMg(OR')2}.cR'OH}, wherein R' is selected from a hydrocarbon group, X is selected from a halide group, and a:b:c is in range of 0.1-99.8 : 0.1-99.8 : 0.1- 99.8, and a process for preparing the same. The said process comprises contacting a magnesium source with an organohalide and alcohol in a solvent to form the liquid organomagnesium precursor. The present invention also provides a catalyst system using the organomagnesium precursor and its use thereof for polymerization of olefins.
