摘要

The tripodal bipyridine-based ligand tris(2,2’-bipyrid-6-yl) methanol (L 1 ) was shown in our previous workto 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 perchloratecounterion. 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) ?, α = 90°, β = 110.790(1) °, γ = 90°, volume = 5855.4(2) ?3, 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 bipyridinegroups were equivalent.We report the crystal structure of the protonated form a tripodal bipyridine-based ligand framework with a strongsteric preference for trigonal prismatic co-ordination environments.
