CH3GeH3
Methylgermane is a chemical compound with the formula CH3GeH3. It is a germyl derivative of methane, where a methyl group (CH3) is attached to a germyl group (GeH3). This compound is a colorless gas at room temperature and pressure. It belongs to the class of organogermanium compounds, which feature a germanium-carbon bond. Methylgermane is structurally analogous to silanes and alkanes, with germanium replacing a carbon atom in a similar arrangement. Its physical properties, such as boiling point and density, are generally influenced by the heavier germanium atom compared to its carbon or silicon counterparts. Methylgermane is often synthesized through reactions involving germanium halides and methylating agents. Its reactivity is characteristic of germanes, undergoing reactions such as dehydrogenation and substitution. It can also participate in polymerization reactions to form polysilanes or polygermanes. Due to its potential use as a precursor in materials science, particularly for the deposition of germanium-containing thin films via chemical vapor deposition (CVD) techniques, methylgermane has been a subject of scientific study. These films can find applications in electronics and optoelectronics. Handling methylgermane requires precautions due to its potential flammability and toxicity.
