Hypothesis
The study investigates the synthesis of a dithiolate bridged Ni-Fe complex to mimic the active site structure of Ni-Fe hydrogenase.
Conclusion
The research successfully isolated a trinuclear Fe–Fe–Ni complex, demonstrating ligand reshuffling in the process.
Supporting Evidence
- The complex is the second example of M(μ-SR)2Ni(CO)2 coordination.
- Both FeII ions are five-coordinated in distorted trigonal–bipyramidal geometries.
- The Ni atom is four-coordinated in a distorted tetrahedral geometry.
Takeaway
The researchers tried to create a special metal complex but ended up with a different one that still has interesting properties.
Methodology
The complex was synthesized in methanol solution and characterized using crystallography.
Limitations
The identity of the brown powder obtained during synthesis was not determined.
