The synthesis and characterization of Li[O 2 P{OCH(CF 3 ) 2 } 2 ] ( 1 ) was investigated together with a new synthesis for Li[O 2 P(OCH 2 CF 3 ) 2 ] ( 2 ). The electrochemical properties of both lithium bis(fluoroalkyl)phosphates were investigated. Compound 2 was prepared by deprotonation of the conjugate acid HO(O)P(OCH 2 CF 3 ) 2 ( 3 ), of which the crystal structure was solved. Lithium bis(fluoroalkyl)phosphates 1 and 2 were used to prepare gel electrolytes on the basis of a coordination network held together solely by ionic interactions between the lithium ions and the anions. The preparation of the gel electrolytes produced with 2 and their properties were explored.
