Four lanthanide derivatives of Ta-containing POMs [Ln(3)(H2O) (22)][P2W15Ta3O62].nH2O (Ln = La, 1; Ce, 2; Pr, 3; and Nd, 4) were isolated by the self-assembly of Wells-Dawson type Ta/W mixed- addendum POM and lanthanide ions. Compound 1 showed excellent proton conduction performance at high relative humidities (RHs), with conductivity reaching 1.26 x 10(-2) S cm(-1) at 95 degrees C under 98% RH.
