✦ Synopsis

The [(P 4 W 34 O 61 ) 2 {Mo 4 S 4 O 4 (OH 2 ) 2 }] 16-anion was obtained by the stereospecific addition of the [Mo 2 S 2 O 2 ] 2+ oxothio cation to the monovacant α 2 -[P 2 W 17 O 61 ] 10-anion. The mixed salt K 9 Na 7 [(P 2 W 17 O 61 ) 2 {Mo 4 S 4 O 4 (OH 2 ) 2 }]•50H 2 O was isolated as single crystals and characterized by X-ray diffraction. The analysis reveals that the anion adopts a "sandwich-like" dimeric structure in which the two α 2 -[P 2 W 17 O 61 ] 10-subunits are assembled in a transoid disposition with respect to the central cluster {H 4 Mo 4 S 4 O 6 }. In aqueous solution, an isomer-
