Phosphine oxidation state
WebThe oxidation number of phosphorus in phosphine (PH3) is -3, similar to that of nitrogen in ammonia (NH3). Phosphine is the normal hydride of phosphorus and this nonmetal is … WebMar 6, 2024 · Phosphine doesn't form dihydrogen gas on contact with water so $\ce{H}$ is in oxidation state +1 and $\ce{P}$ is in oxidation state -3. Reaction with strong acids leads to $\ce{PH4+}$ which has similar structure to the ammonium ion. For these reasons even for $\ce{As}$ in $\ce{AsH3}$ the oxidation state of $\ce{As = -3}$.

WebFeb 1, 2024 · There is a complex relationship between M–P distance and oxidation state in low valent metals. In some cases, oxidation may increase the metal–ligand distance, which is sometimes attributed to loss of π-backbonding (ϕ) [11], [12]. However, oxidation may increase or decrease M–P distances. Web摘要： Phosphines and related ligands (PE3) are some of the most versatile and well-studied in the chemist's arsenal. The vast majority of studies on these ligands have focused on their interactions with low valent transition metals.
