Zusammenfassung:Mixed oxides of formula (A) X a Y b Z c O d .pC (A) or sulfided metal catalysts useful as hydrotreating catalysts and obtained by the sulfidation of mixed oxide precursors of formula (A) or of mixed oxides of formula (A), in shaped form with a binder, where X = Ni, Co or a mixture thereof, Y = Mo, W or a mixture thereof, Z = Si, Al or a mixture thereof, C is a nitrogenated compound N or an organic residue thereof, a, b, c, d = number of moles, p = wt.-% of C, a, b, c, d > 0, a/b >= 0.3 and =0.3 and 10, d = (2a+6b+Hc)/2 wherein H = 4 when Z = Si or H = 3 when Z = Al and p >= 0 and
