For tailoring the size and morphology of nanoparticles, a deep knowledge of the mechanism leading to particle formation is required. We have investigated the reaction mechanisms in the synthesis of anatase nanocrystals by the so‐called benzyl alcohol route as a model for binary metal oxides, and elucidated the chemical structure of cluster species involved in the reaction using NMR spectroscopy and single crystal X‐ray structure analysis. In the first reaction step, a novel dimeric coordination complex is formed via ligand exchange, and was identified as the crucial compound initiating particle formation in the synthesis process.
