Conclusion
The study presents a new polymorph of a cobalt(II) complex that exhibits a unique agostic interaction.
Supporting Evidence
- The new polymorph was formed through a ligand displacement reaction.
- The cobalt(II) complex exhibits a distorted octahedral coordination geometry.
- The study supports the existence of a B—H⋯Co agostic interaction.
- Infrared spectral results indicate the presence of bound B—H groups.
Takeaway
Scientists discovered a new version of a cobalt compound that has a special bond with hydrogen, which helps it hold its shape.
Methodology
The compound was synthesized and characterized using X-ray crystallography.
