Great balls of tungsten : Two polyoxotungstates with spectacular size (almost 1000 atoms), molar mass (approximately 33 000 g mol −1 ), and spherical symmetry have been synthesized. The dimethyltin‐substituted [{Sn(CH 3 ) 2 (H 2 O)} 24 {Sn(CH 3 ) 2 } 12 ( A‐ XW 9 O 34 ) 12 ] 36− ions (see polyhedral representation; X=P, As; red octahedra WO 6 , yellow tetrahedra XO 4 ) consist of 12 ( A‐ XW 9 O 34 ) Keggin moieties linked by 36 dimethyltin groups resulting in a spherical structure with a cavity 8 Å in diameter.
