A dinuclear double-helical complex of potassium ions with a
compartmental bridging ligand containing two terdentate N-donor
fragments
The compartmental bridging ligand bis{3-[6′-(2,2′-bipyridyl)]pyrazol-1-yl}hydroborate (L - ), which contains two chelating terdentate N-donor arms linked by an anionic –BH 2 – bridge, forms a dinuclear double-helical complex K 2 L 2 with K + ions.
