Fe3form

Fe3form is a term encountered in chemistry, materials science, and product naming, but it does not have a single, universally accepted definition. In chemical literature, Fe3form has been used to describe a class of trinuclear iron motifs, where three iron centers are connected by bridging ligands, forming a Fe3 core. In other uses, it appears as a brand or product name for iron-containing formulations or pigments. Because the term is not standardized, interpretations vary by source.

Composition and structure: When used in coordination chemistry contexts, Fe3form commonly refers to clusters with three iron atoms (often FeIII) linked by shared ligands, forming triangular cores. Ligand sets may include carboxylates, amines, or phenolates, and bridging groups such as oxo, hydroxo, or alkoxo.

Synthesis: Reported syntheses typically involve controlled assembly from iron salts under programmable oxidation states, in the presence of supporting ligands, solvents, and sometimes templating agents. Conditions influence the nuclearity, oxidation state distribution, and crystallinity.

Properties and applications: Fe3form-associated clusters exhibit magnetic interactions and variable oxidation states. They are studied for fundamental coordination chemistry, catalysis, and materials science. Product names bearing Fe3form often target pigments, coatings, or specialty catalysts.

History: Because Fe3form is not a standardized chemical term, its meaning arises from context—academic papers, supplier catalogs, and patent literature. This ambiguity means specific definitions should be confirmed against the source in use. See also iron clusters, trinuclear complexes, and coordination polymers.
