Arsenic Tetraoxide

Arsenic tetraoxide is a chemical compound with the formula As4O6. It is also known as arsenic(III,V) oxide or diarsenic tetraoxide. The compound exists as a white or yellowish powder and is highly toxic.

The structure of arsenic tetraoxide consists of two As2O3 units joined by a bridging oxygen atom. Each As2O3 unit has a trigonal planar shape, with the arsenic atom at the center and three oxygen atoms arranged symmetrically around it. The bridging oxygen atom is bonded to two arsenic atoms, forming an As-O-As bridge.

Arsenic tetraoxide is primarily used in the production of glass and ceramics, as well as in the manufacturing of certain types of semiconductors. It can also be used as a pesticide or herbicide, but its use for these purposes is highly regulated due to its toxicity.

Exposure to arsenic tetraoxide can cause a range of health problems, including skin irritation, respiratory issues, and cancer. It is important to handle this compound with extreme care and to follow proper safety procedures when working with it.
