摘要：

Germanium dioxide crystallites can be generated via a delayed precipitation in a mixture of germanium ethoxide and hydrochloric acid. This delay is often described as an induction period wherein polymeric structures are formed from the monomer to the nuclei. We have investigated this mixture by electrospray mass spectrometry during this period. Mono and oligo germanium acids as well as chloro germanium acids were observed. Quantum chemical calculations were used to discuss essential features of their composition and structures. Moreover possible reaction pathways for the growth of the oligo germanium acids and chloro oligo germanium acids are discussed.
