The synthesis of two novel molecular organotelluroxane clusters are described, wherein Te(iv) centred electrophilicity is crucial in the chalcogen bonding anion template directed assembly. These assemblies exhibit aggregation induced emission (AIE).

An easy, direct and room temperature silicon-carbon bond activation is reported. The reaction of [RhCl(coe)2]2 with the silane Si(Me)2(o-C6H4SMe)2 in the presence of an halide extractor provokes a Si-CH3 bond cleavage yielding a cationic silyl-methyl

The sequential solid/gas single-crystal to single-crystal reaction of [Rh(Cy2P(CH2)3PCy2)(COD)][BArF4] (COD = cyclooctadiene) with H2or D2was followed in situ by solid-state31P{1H} NMR spectroscopy (SSNMR) and ex situ by solution quenching and GC-MS.
