Dihydrogenphosphates with the general formula Zn1-x(H2O4)222 (0 <  < 1) and phosphates of composition Co3-Mg(PO4)282 (0 <  ≤ 1) were synthesized. The former crystallize in the monoclinic system, space group 21/n (Z = 2), with the formation of a continuous substitutional solid solution. The latter form a limited solid solution. Their catalytic properties were investigated. The effectiveness of their action as catalysts for alcohol dehydration and methane oxidation was shown.
