A process for making a catalyst precursor is disclosed. In one embodiment, the process comprises co-precipitating at reaction conditions forming a precipitate or cogel: at least a promoter metal compounds selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least one of Group VIB metal compounds, at least an organic oxygen-containing ligand L. The precursor is represented by the formula Av[(MP) (OH)x(L)ny]z(MVIBO4), wherein A comprises an alkali metal cation, an ammonium, an organic ammonium or a phosphonium cation, MP is at least one of Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, L is the organic, oxygen-containing co-ordinating ligand, MVIB is at least one of Group VIB metals, and the atomic ratio of MP:MVIB is between 100:1 and 1:100.

What is claimed is: 1. A process for forming an unsupported catalyst precursor composition having a formula Av[(MP) (OH)x(L)ny]z(MVIBO4), the process comprises the steps of: co-precipitating at reaction conditions forming a precipitate or cogel comprising: at least a metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least a Group VIB metal compound, at least one organic oxygen-containing ligand, wherein A is at least one of an alkali metal cation, an ammonium, an organic ammonium and a phosphonium cation, MP is at least one of a Group VIII metal, Group IIB metal, Group IIA metal, Group IVA metal and combinations thereof, P is oxidation state with MP having an oxidation state of either +2 or +4 depending on the selection of MP, L is at least one organic oxygen-containing ligand, MVIB is at least a Group VIB metal, having an oxidation state of +6, MP:MVIB has an atomic ratio of 100:1 to 1:100, v−2+P*z−x*z+n*y*z=0; and 0<y≦−P/n; 0<x≦P; 0<v≦2; 0<z; and performing a solid-liquid separation to collect the unsupported catalyst precursor. 2. The process of claim 1, wherein MP is at least a Group VIII metal, MVIB is selected from molybdenum, tungsten, and combinations thereof. 3. The process of claim 1, wherein MP is nickel (Ni), and wherein Ni:(Mo+W) has a molar ratio of 10:1 to 1:10. 4. The process of claim 1, wherein L is negatively charged. 5. The process of claim 1, wherein L is at least one of carboxylates, enolates, and combinations thereof. 6. The process of claim 1, wherein the at least one organic, oxygen-containing ligand L is maleate. 7. The process of claim 1, wherein at least the metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof is a water soluble cobalt salt, the at least one Group VIB metal salt is selected from ammonium hexamolybdate, ammonium metatungstate, and combinations thereof. 8. The process of claim 1, further comprising the step of extruding the catalyst precursor to form an extrudate. 9. The process of claim 8, further comprising the step of adding a cellulose containing material to the catalytic precursor prior to extruding the mixture to form an extrudate. 10. The process of claim 8, wherein the extrudate is dried at a temperature ranging from 50-250° C. 11. The process of claim 1, further comprising the step of sulfiding the catalyst precursor thus forming a catalyst. 12. The process of claim 8, further comprising the step of sulfing the extrudate. 13. The process of claim 1, wherein MP is a mixture of Ni and Co. 14. The process of claim 1, wherein MP is Sn. 15. The process of claim 1, wherein MP is Zn.
