Claim:
1. A process for preparation of a solid organomagnesium precursor having formula {Mg(OR′) X}.a{MgX 2 }.b{Mg(OR′) 2 }.c{R′OH}, wherein R′ is same and is selected from a hydrocarbon group, X is selected from a halide group, and a:b:c is in range of 0.01-0.5:0.01-0.5:0.01-5, said process comprising contacting a magnesium source with a solvating agent, an organohalide and an alcohol to obtain the solid organomagnesium precursor, wherein the solvating agent is selected from a group consisting of dimethyl ether, diethyl ether, dipropyl ether, diisopropyl ether, ethylmethyl ether, n-butylmethyl ether, n-butylethyl ether, di-n-butyl ether, di-isobutyl ether, isobutylmethyl ether, and isobutylethyl ether, dioxane, tetrahydrofuran, 2-methyl tetrahydrofuran, tetrahydropyran and combination thereof.
