E. Psillakis et al., A DINUCLEAR DOUBLE-HELICAL COMPLEX OF POTASSIUM-IONS WITH A COMPARTMENTAL BRIDGING LIGAND CONTAINING 2 TERDENTATE N-DONOR FRAGMENTS, Chemical communications, (5), 1997, pp. 479-480
The compartmental bridging ligand is{3-[6'-(2,2'-bipyridyl)]pyrazol-1-
yl}hydroborate (L(-)), which contains two chelating terdentate N-donor
arms linked by an anionic -BH2- bridge, forms a dinuclear double-heli
cal complex K(2)L(2) with K+ ions.
