Abstract:
In acetonitrile solvent, Fe(5)(CO)(15)(mu(5)-C), 1, reacts with Ni(COD)(2) at room temperature to afford the iron-nickel complex Fe(5)Ni(NCMe)(CO)(15)(mu(6)-C), 3. The acetonitrile ligand in 3 can be replaced by CO and NH(3) to yield Fe(5)Ni(CO)(16)(mu(6)-C), 4, and Fe(5)Ni(NH(3))(CO)(15)(mu(6)-C), 6, respectively. When refluxed in acetonitrile solvent, compound 3 loses a vertex to form the square pyramidal Fe(4)Ni complex Fe(4)Ni(NCMe)(2)(CO)(12)(mu(5)-C), 7. Compound 7 readily converts to Fe(4)Ni(NCMe)(CO)(13)(mu(5)-C), 8, by losing one of its acetonitrile ligands. Addition of acetonitrile to 8 gives compound 7. When heated to 110 degrees C under an atmosphere of CO, both compounds 7 and 8 furnish the octahedral Fe(4)Ni(2) complex Fe(4)Ni(2)(CO)(15)(mu(6)-C), 9. All six compounds were structurally characterized by single-crystal X-ray diffraction analyses.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
