The symmetry of the hexatungstoplatinate(IV) anion in Na 8 [PtW 6 O 24 ]Á26H 2 O is C i (1), which is different from the D 3d (3m) and S 6 (3) symmetry found in K 6 Na 2 [PtW 6 O 24 ]Á-12H 2 O and (CH 6 N 3 ) 8 [PtW 6 O 24 ], respectively. However, this change in symmetry does not signi®cantly affec
