If you read this post, you shouldn't be surprised to see they used the tungsten compund to make bimetallic complexes. I mean they even mentioned it in the paper as far as I can remember. So here we go, probably the first of the series of biemtallic complexes. Depending on the alkyne substituents, they can tune the redox potentials as expected. The real interesting part is that alkyne can rotate in this bimetallic complex while it is not observed for the tungsten compound. I like this group's work. Looking forward to the next paper.
