Larger Metaphosphate Rings

Some hexametaphosphates can be obtained directly by heating an appropriate acid triphosphate. [Pg.244]

Mixed-cation hexametaphosphates can be obtained by reactions such as [Pg.244]

Isostructural rare earth hexametaphosphates include M2P6O18 IOH2O, where M = La, Ce, Pr, Sm, Er, Yb (monoclinic and orthorhombic series). [Pg.244]

Some hexametaphosphates revert to tetrametaphosphates on heating (5.178) while others revert to long-chain polyphosphates (5.179). [Pg.244]
