Abstract
Abstract A new layered magnesium zinc phosphate hydrate, MgZn(HPO 4 ) 2 ·H 2 O, with a zinc phosphate framework isostructural with the one of Na 2 Zn(HPO 4 ) 2 ·4H 2 O, was prepared by the direct ambient pressure and temperature reaction between zinc 2,4-pentanedionate, phosphoric acid and hexahydrated magnesium chloride. The as-prepared sample is monoclinic ( a = 8.780(7) A, b = 13.240(7) A, c = 11.123(0) A and β = 116.21(2)°). The prepared solid undergoes two thermal transformations when it is heated from 110 to 600 °C. The first transformation is due to the release of intercalated water molecules and the second one is due to the HPO 4 2− → P 2 O 7 4− transition.
