K15[(LnO)3(PW9O34)2].xH2O (Ln = La, Ce, Pr, Nd, Sm, Eu or Gd) were prepared from lacunary Na8HPW9O34 and characterized by elemental anal., vibrational and UV spectroscopies. 31P NMR establishes that PW9O349- in heteropolyanions [(LnO)3(PW9O34)2]15- has an A-type structure. Polarog. data indicates that it is an A, a isomer.
