Abstract

The tripodal bipyridine-based ligand tris(2,2’-bipyrid-6-yl) methanol (L 1 ) was shown in our previous work to have a strong steric preference for trigonal prismatic co - ordination environments with a series of transition metals. We now report the crystal structure of the ligand framework, isolated in its monoprotonated form with a perchlorate counterion. The structure was solved in a monoclinic space group C2/c with cell parameters, a = 21.5885(3), b = 11.7485(3), c = 24.6939(6) Å, α = 90°, β = 110.790(1) °, γ = 90°, volume = 5855.4(2) Å3 , Z = 8. The 1H NMR of the protonated ligand is similar to the parent ligand and showed the compound retained its 3-fold symmetry and all bipyridine groups were equivalent.

We report the crystal structure of the protonated form a tripodal bipyridine-based ligand framework with a strong steric preference for trigonal prismatic co-ordination environments.

Keywords: Bipyridine, crystal structure, trigonal prismatic, tripodal ligand.

I am completely satisfied with the service I received from Bentham Science Publishers, right from the submission of our research paper in ‘Open Chemistry’ to its publication in the journal. The reviewers' and editor's comments were very helpful in improving the paper.

I take this opportunity to express my appreciation to the whole team of BSP!
