Alkaline earth, transition and lanthanide metal inorganic salt complexes

摘要

Novel metallo-organic complexes of the formula (M_xX_z.nL)_y where M is an alkaline earth metal, a transition metal (at. Nos. 21-30, 39-48 and 72-80 inclusive) or a rare earth metal (at. Nos. 57-71 inclusive), X is an anion e.g. Cl⁻, Br⁻, NO₃⁻ NCS⁻ etc. and L is a Lewis base, are prepared by reacting a source of the metal M under anhydrous conditions with an anhydrous ammonium salt of the anion X in the presence of the Lewis base, and cooling the reaction mixture to precipitate the complex.
