This patent describes a hydrocracking process comprising contacting a hydrocarbon feed at a temperature of at least about 100/sup 0/C. and in the presence of hydrogen, with a catalyst obtained by compositing a quantity of inorganic refractory oxide support material and a hydrated oxide of trivalent chromium with one or more precursor salts and heating the composite at elevated temperature of at least about 150/sup 0/C. The composite is heated in the presence of sulfur or sulfur bearing compound and under oxygen-free conditions for a time sufficient to form the catalyst. The precursor salt contains a tetrathiometallate anion of Mo, W or mixture thereof and a cation comprising the conjugate acid of one or more neutral, nitrogen-containing ligands, L, at least one of which is a chelating polydentate ligand. The feed contacts the catalyst for a time sufficient to hydrocrack at least a portion of the feed.
