Dihydrogenphosphates with the general formula Zn1-õÑîx(H2ÐO4)2·2Í2Î (0 < õ < 1) and phosphates of composition Co3-õMgõ(PO4)2·8Í2Î (0 < õ ≤ 1) were synthesized. The former crystallize in the monoclinic system, space group Ð21/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.
