I tried out the new feature by applying (j,j) Cp-ligand and (J,J) Pi-benzene ligand on a 'Fe' atom. Interestingly when I applied the 3D Clean Up feature onto the molecules the Fe-Cp-ligand showed an irregular Cp arrangement. When a 90-degree turn is applied to the 3D structure we can see that the Cp ring is detached/ 3D Clean Up breaks the Cp ring completely (screenshot 1). A similar feature is seen when a 90-degree turn is applied onto Fe-Pi-benzene where the Fe atom is far away from the ligands (Screenshot 2)
I also copied the structures as 3MF and pasted them onto Powerpoint (Screenshot 3). The Fe-Cp-ligand shows a clear disoriented Cp ligand + The Colour scheme of the Fe atom and the bonds make it appear like a 'water' molecule (Screenshot 3). I've drawn H2O molecule for a direct comparison
Getting multi-center attachments to behave properly in 3D is in the works as we speak.
