Cool abstract picture of the day and a Lack of binding

The Gardinier group at Marquette Univ. have developed a new pentadentate ligand alpha,alpha,alpha',alpha'-tetra(pyrazolyl)lutidine. They just published their first paper in Inorganic Chemistry about it, and it will be the first in a series. It's made by four pyridines bound to another pyridine and a couple of tertiary or quaternary carbons, resulting in the five nitrogens of the pyridines being available for binding. Their abstract image is below; I approve. It reminds me of the image which appears in my head when I think about the Scorpionates by Trofimenko.



This paper talks about how the ligand binds to first-row transition metal halides. What it doesn't talk about is the binding itself. In fact, a search of both the article and the SI only shows any variation of the word 'bind' appearing twice. I would think a discussion of binding constants would be the most important aspect of discovering a new multidentate ligand for metals? This isn't even mentioned when they talk about future work.

The focus is on the XRD structures and UV-vis spectra of these complexes, as well as the synthesis. It's an interesting ligand, and what they've done so far is nice work; will be interesting to see where they go with this.

Godspeed.
