Abstract

GRAPHICAL ABSTRACT: ABSTRACT: In a systematic study of the physico-chemical properties of cyclotriphosphates of alkaline earth cations Type M II M I P3 O9 .xH2 O carried out in our laboratory. (M II = Ca 2+, Sr 2+, and Ba 2+ ) and (M I = Rb +, K +, Cs +, and NH4 + ). We are interested in the synthesis of the mixed barium cyclotriphosphate associated with the cesium ion. Chemical preparation and crystal structure are reported for a barium cesium cyclotriphosphate dihydrate BaCsP3 O9 .2H2 O. The phosphoric ring anions are interconnected by BaO8 dodecahedra in the structure of BaCsP3 O9 .2H2 O. The two water oxygens in the present arrangement participate in the coordination spheres of the associated barium and cesium cations. The thermogravimetric analysis shows that the removal of these two water molecules occurs in two stages between 105 and 600°C. The vibrational study by IR absorption spectroscopy of the title compound reveals the presence of P3 O9 ring and confirms the existence of nonequivalent positions of water molecules in the structure.
