User:Graeme Bartlett/arsenide carbide
Arsenide carbides or carbide arsenides are compounds containing
mixed anion compounds. Related compounds include the arsenide silicides, germanide arsenides, and phosphide carbides
.
Some of these compounds are what are called MAX phases, where M is a metal and A and X are main group elements. Ratios can be 2:1:1 or 3:2:1.
Another class is perovskite carbides of the form M3AsC.
The bonds between the metal and arsenic can be classified as metallic, but between the metal and carbon are covalent.
