Crystal structure of caesium dimethyl-N-benzoylamidophosphate monohydrate

The caesium salt of dimethyl-N-benzoylamidophosphate, namely, aqua[dimethyl (N-benzoylamido-kappa O)phosphonato-kappa O]caesium, [C-s(C9H11NO4P)(H2O)] or CsL(.)H2O, is reported. The compound crystallizes in the monoclinic crystal system in the P2(1)/c space group and forms a mono-periodic polymeric structure due to the bridging function of the dimethyl-N-benzoylamidophosphate anions towards the caesium cations.
