  Triiron dodecarbonyl (CAS NO.17685-52-8), its Synonyms are Di-mu-carbonyldecacarbonyl-triangulo-triiron ; Iron, di-m-carbonyldecacarbonyltri-,triangulo ; Ironcarbonyl (Fe3(CO)12) (6CI) ; Iron, di-m-carbonyldecacarbonyltri-, triangulo- (8CI) ; Dodecacarbonyl-triangulo-triiron ; Dodecacarbonyltriiron;Dodecacarbonyltriiron(0) . It is soluble in nonpolar organic solvents to give intensely green solutions. Most low nuclearity clusters are pale yellow or orange. Hot solutions of Triiron dodecarbonyl decompose to an iron mirror, which can be pyrophoric in air. The solid decomposes slowly in air, and thus samples are typically stored cold under an inert atmosphere.
