The synthesis of a newcharge-neutral zwitterionic tripodal borateligand based on 2-hydroxypyridine is reported. (Dimethylaminopyridinium)tris(2-pyridonyl)borate, (DMAP)Thp, has been complexed to copper(I) chloride to give a pseudo-C(3) symmetric complex. The propensity for this ligand and other flexible scorpionates to exhibit such helical chirality upon complexation is discussed.
