Ionic liquid compound

A process for the preparation of an ionic liquid compound of Formula (I),

• wherein,
• NR1R2R3 represents an amine,
• R1, R2 and R3 are independently selected from the group consisting of alkyl, aryl and H,
• M1 or M2 is a metal selected from the group consisting of Al, Fe, Zn, Mn and Mg, Ti, Sn, Pd, Pt, Rh, Cu, Cr, Co, Ce, Ni, Ga, In, Sb, Zr and combinations thereof,
• X or Y is selected from the group consisting of halogen, nitrate, sulphate, sulfonate, carbonate, phosphonate and acetate, ‘n’ represents 1 to 4,
• ‘i’ represents 1 to 6,
• ‘j’ represents 1 to 4,
• ‘k’ represents 1 to 4,
• ‘L’ represents 1 to 7,
• M1=M2 or M1≠M2, and
• X═Y or X≠Y,
• said process comprising the following steps:
• i. preparing an ionic salt complex precursor represented by Formula [(NR1R2R3)iM1]n+[Xj]n− by mixing an amine represented by Formula NR1R2R3 and a metal salt represented by formula M1Xj;
• and
• ii. mixing the ionic salt complex precursor and a metal salt represented by formula M2Yk to obtain the ionic liquid compound.
