LXH}2 ligands have no net charge, however, as the pendant heterocycles are both protonated. X-ray crystallographic studies revealed that the two outer-sphere N–H groups form intramolecularhydrogen bonds with the chlorido ligands. Modification of the syntheses provided CuII complexes (i.e., 2X, 3X) that contain an aqua ligandhydrogen bonded to the outer-sphere group(s). Whereas complexes with the
