A process is described for hydrotreating a hydrocarbon feed which comprises contacting the feed at a temperature of at least about 150/sup 0/C. and in the presence of hydrogen with a catalyst obtained by compositing a quantity of inorganic refractory oxide support material with one or more precursor salts and heating the composite at elevated temperature of at least about 150/sup 0/C. This is done in the presence of sulfur or sulfur bearing compounds and under oxygen-free conditions for a time sufficient to form the catalyst, wherein the precursor salt contains a tetrathiometallate anion of Mo, W or mixture thereof and a cation comprising at least one promoter metal selected from the group consisting of (a) divalent iron and (b) mixtures of divalent iron with one or more metals selected from the group consisting of divalent Ni, Co, Mn, Cu, and Zn wherein the divalent promoter metal or metals are chelated by at least one neutral, nitrogen-containing polydentate ligand, L. The contacting occurs for a time sufficient to hydrotreat at least a portion of the feed.
