yttrium‐pillared silicotungstate dimer (see picture) catalyzes the cyanosilylation of structurally diverse ketones and aldehydes with trimethylsilyl cyanide (TMSCN). The reactions proceed selectively and afford the corresponding cyanohydrin trimethylsilyl ethers. The catalytic performance is significant, in particular for aldehydes, with a turnover number of 18 000 and a turnover frequency of 540 000 h−1

cyanosilylation of carbonyl compounds. For acetophenone: (i) the coordination number and μ-OH groups presence seem to be decisive factors to obtain a better catalytic behavior and (ii) the presence of Lewis base moieties (CO groups not coordinated to indium cation), besides the Lewis acid sites, creates a two-component catalytic system, based on the “dual activation” phenomenon that makes InPF-15 the best catalyst

performed on two representative low-dimensional compounds in order to find the relationships between their structural features and their intrinsic mechanical properties (hardness and elasticity). The solid-state photoluminescence (SSPL) properties were also studied in terms of excitation, emission, lifetimes values, and CIE chromaticites. Moreover, the heterogeneous catalytic activities of the compounds
