A new metal polyphosphate, α-CsBa2(PO3)5, exhibiting the first example of a linear P-O-P bond angle in a one-dimensional (PO3)∞ chain has been reported. Interestingly, α → β phase transition occurs in CsBa2(PO3)5 along with the P-O-P bonds varying from linear to λ-shape, suggesting that α-CsBa2(PO3)5 with unfavorable linear P-O-P bonds is more stable at ambient temperature.
