The application of bisthiometalato complexes of the type [M′(MS4)2]n−(n= 2 or 3, M′ = Co or Ni, and M = Mo or W) as precursors for the preparation of hydrotreating catalysts was investigated. The thermal decomposition of the tetraethylammonium salts of these complexes in an H2H2S atmosphere at 400°C leads to the formation of catalytically active materials which were characterized by physico-chemical methods and their catalytic activities in biphenyl hydrogenation. As the molecular structures of the starting complexes are known, the resulting catalysts can be discussed as “modified precursors”. Structural models of these catalysts have been developed on the basis of this assumption and the present results.
