Dicaesium tetra-magnesium penta-kis-(carbonate) deca-hydrate, Cs2Mg4(CO3)5·10H2O.


ABSTRACT: The title carbonate hydrate, Cs2Mg4(CO3)5·10H2O, was crystallized at room temperature out of aqueous solutions containing caesium bicarbonate and magnesium nitrate. Its monoclinic crystal structure (P21/n) consists of double chains of composition 1 [Mg(H2O)2/1(CO3)3/3], isolated [Mg(H2O)(CO3)2]2- units, two crystallographically distinct Cs+ ions and a free water mol-ecule. The crystal under investigation was twinned by reticular pseudomerohedry.
