Trithioarsenite

File:SubunitProustite.jpg

Subunit of the structure of proustite, a sulfosalt mineral. This picture shows the connectivity of the trithioarsenite trianion to Template:Chem2 (arsenic is colored violet).

Trithioarsenite, also called sulfarsenite, is the trianion Template:Chem2. It is a pyramidal anion, as is typical of other Template:Chem2 compounds. It is generated by treatment of [[Arsenic trisulfide|Template:Chem2]] with a sulfide:

Template:Chem2

A fundamental synthetic trithioarsenite is Template:Chem2, which features the pyramidal Template:Chem2.

Thioarsenites are components of many sulfosalt minerals. An example is relatively common mineral proustite, Template:Chem2, which is silver(I) trithioarsenite.
