Fe3Fe2

Fe3Fe2 is not a widely recognized chemical compound. In the context of chemistry and materials science, the symbol Fe denotes iron, so a formula of Fe3Fe2 would superficially imply a compound composed only of iron atoms in a 3:2 ratio. Since both parts are iron, the formula simplifies to Fe5, which is not itself a standard or well-characterized binary iron compound. Consequently, Fe3Fe2 does not represent a distinct, well-defined phase in common materials databases.

In practice, Fe3Fe2 is more likely to be encountered as either a typographical error or as shorthand for an ordering model within a single iron-containing alloy rather than a discrete compound. Some sources may use it to describe a site-ordered intermetallic where two iron sublattices are present in a 3:2 ratio, but without specifying a second element this is not a complete chemical designation. If other elements are present (for example as Fe-Fe-X systems), Fe3Fe2 could reflect a composition window or minority phase in an alloy, but the exact interpretation depends on the source.

Because there is a wide range of iron-based intermetallics and carbides, researchers typically reference known compounds such as cementite (Fe3C), ferrite (Fe), and austenite when discussing materials properties. Fe3Fe2 itself is not listed as a standard compound in major crystallographic or phase-diagram databases, and its meaning is usually clarified by the context in which it appears. Related topics include the iron–carbon phase diagram and various iron-based intermetallics.
