I am not sure if it is free, but looks like I was able to view it without using my school's access. Maybe I was already logged in. Don't know.
So, they prepared a new ligand and three metal complexes (two of them bimetallic) with it. Maybe I'll do one of these one day.
Looks like they couldn't obtain crystals for the bimetallic complexes. They only report the ligand and the mono complex.
