A catalyst precursor composition and methods for making such catalyst precursor is disclosed. The catalyst precursor comprises at least one of a Group IIB metal compound, a Group IVA metal compound, a Group IIA metal compound, and combinations thereof, at least one Group VIB metal, at least one organic, oxygen-containing ligand, and optionally a cellulose-containing material. Catalysts prepared from the sulfidation of such catalyst precursors are used in the hydroprocessing of hydrocarbon feeds. In one embodiment, the catalyst precursor is of 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 selected from Group IIB, Group IVA and combinations thereof, having an oxidation state of either +2 or +4; L is at least one organic, oxygen-containing ligand, MVIB is at least one 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.
