Wheel meet again : The titanium( IV ) substituted [{β ‐ Ti 2 SiW 10 O 39 } 4 ] 24− ( 1 ) consists of four β ‐ Keggin moieties that are linked via Ti‐O‐Ti bonds leading to a cyclic arrangement (see picture; red WO 6 , green TiO 6 , and blue SiO 4 ). The wheels stack to give a tunnel‐like structure. Synthesis of 1 is from the dilacunary precursor [γ ‐ SiW 10 O 36 ] 8− and gives insights into the mechanism of formation of polyoxoanion assemblies.
