Abstract
This invention relates to heterometallic thiocubane compositions containing the M.sub.2.sup.1 M.sub.2.sup.2 S.sub.4 cluster core and methods of making them wherein M.sup.1 is Re, V, Mo or W and M.sup.2 is Co, Cr, Cu, Ni or Fe but preferably Co. More particularly, the invention relates to compositions of the formula M.sub.2.sup.2 M.sub.2.sup.2 S.sub.4 L.sub.2.sup.1 L.sub.2.sup.2 L.sub.2.sup.3 wherein M.sup.1 and M.sup.2 are as above, L.sup.1 is a bidentate sulfur or nitrogen bearing ligand (most preferably a dialkyldithiocarbamate), L.sup.2 is optional but may be an O, N, P or S-containing monodentate donor ligand, and L.sup.3 may be CO, a monodentate anion ligand such as a halide (preferably C1), mercaptide or alkoxide, or another O, N, P, or S containing monodentate donor ligand. The compositions are suitable for making active hydrotreating catalysts.
