A compound having a triangular or bigger closed polyhedron of metal atoms is the best definition of a cluster compound. Fe2(CO)9 and Fe3(CO)12 were easily isolated as a result of the formation of metal carbonyl clusters such as Ni(CO)4 and Fe(CO)5. Rundle and Dahl discovered that Mn2(CO)10 included a "unsupported" Mn-Mn link, proving that metals may form bonds with one another in molecules. The synthesis of extremely large clusters from the platinum metals, including [Rh13(CO)24H3]2, was proven by Paolo Chini in the 1970s. Single-crystal X-ray diffraction has been useful in this field of cluster chemistry. Other than CO, ligands are present in many metal carbonyl clusters. For instance, a wide range of substitutes, including phosphines, isocyanides, alkenes, hydrides, etc., can be used in place of the CO ligand. Two or more metals can be found in certain carbonyl clusters. Some of them have carbon vertices. The methylidyne-tricobalt cluster [Co3(CH)(CO)9] is one example. A general zero-charged (neutral) cluster is exemplified by the aforementioned cluster. In addition, cationic organometallic trimolybdenum or tritungsten clusters as opposed to neutral ones are also known. [Mo3(CCH3)2(O2CCH3)6(H2O)3] 2+ is the first of these ionic organometallic clusters that it represents.
