Hypothesis
The study investigates a second monoclinic polymorph of the compound [Ni(C7H6NO2)2].
Conclusion
The new polymorph has similar bond lengths and angles to the previously reported compound but different cell parameters and dihedral angles.
Supporting Evidence
- The new polymorph crystallizes in the space group P21/c.
- Both polymorphs have an internal hydrogen bond.
- The dihedral angle between the layers differs significantly between the two polymorphs.
Takeaway
Scientists found a new version of a nickel compound that looks similar to an old one but has some differences in its structure.
Methodology
The compound was prepared by direct synthesis and analyzed using X-ray crystallography.
