Metalphosphine

Metalphosphine is a chemical compound with the formula P2S3. It is a yellow crystalline solid that is soluble in water and organic solvents. Metalphosphine is a member of the phosphine family, which includes compounds with the general formula PnXm, where n is the number of phosphorus atoms and m is the number of substituents.

Metalphosphine is typically prepared by the reaction of phosphorus trichloride with sodium sulfide. The compound is a Lewis acid, meaning it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond. Metalphosphine is used in the synthesis of various phosphorus-containing compounds, including phosphines and phosphonates. It is also used as a reducing agent in organic synthesis.

Metalphosphine is toxic and can cause irritation to the skin, eyes, and respiratory tract. It is also a potent irritant to the mucous membranes. Prolonged exposure to metalphosphine can cause respiratory failure and death. Therefore, it is important to handle metalphosphine with care and to use appropriate personal protective equipment when working with it.
