Conclusion
The study presents the crystal structure of a cobalt(II) complex with malonate and water, revealing its unique coordination environment.
Supporting Evidence
- The cobalt atom is in an almost octahedral environment formed by malonate ligands and water.
- The structure consists of layers built from edge-sharing KO7 and CoO6 polyhedra.
- Hydrogen bonding connects the layers into a three-dimensional network.
Takeaway
Scientists studied a cobalt compound and found that it has a special shape with cobalt and potassium atoms surrounded by water and malonate molecules.
Methodology
The compound was synthesized using cobalt acetate, imidazole, malonic acid, and KOH, followed by crystallization and X-ray analysis.
