and V.sup.+5, L represents an organic ligand and x, y and q are chosen to
maintain electroneutrality. Further provided are processes for the
production of the inventive DMC catalysts. The crystalline, hydroxide
containing DMC catalysts of the present invention may find use in the
preparation of polyols, such as polyether polyols.
