Deuterated germane, also known as germane-d8 or GeD4, has the CAS number 7782-65-2. It is a deuterated version of germane (GeH4), where the hydrogen atoms are replaced by deuterium atoms. Here are some key characteristics of deuterated germane:
Characteristics of Deuterated Germane (GeD4):
Molecular Formula: GeD4
Molecular Weight: Approximately 116.82 g/mol
Appearance: Colorless gas at room temperature and pressure
Boiling Point: The boiling point of deuterated germane is not readily available, but it is expected to be similar to that of germane (−90.4 °C or 182.75 K).
Melting Point: The melting point is not commonly reported but is expected to be similar to germane (−122.0 °C or 151.15 K).
Density: At standard temperature and pressure (STP), the density is likely to be slightly higher than that of germane (2.42 g/L at 0 °C and 1 atm).
Solubility: Soluble in certain organic solvents, though specific data is not readily available.
Reactivity: Deuterated germane is expected to be less reactive than germane due to the stronger Ge-D bonds compared to Ge-H bonds.
Toxicity: Like germane, deuterated germane is toxic and may pose health risks upon inhalation or skin contact.
Uses:
Deuterated germane is used in various applications including:
Semiconductor Industry: As a precursor for depositing germanium layers on semiconductor wafers.
Organic Synthesis: As a reagent in the preparation of deuterated organic compounds.
Nuclear Magnetic Resonance (NMR) Spectroscopy: As a reference material or solvent.
