The complex (LH)(2)[Cu(NO3)(4)], where L is 1-morpholino-3,3-dimethyl-3,4-d
ihydroisoquinoline, is synthesized and characterized by X-ray crystallograp
hy and IR and electronic spectroscopy. The complex has a cationic-anionic s
tructure. The organic ligand is protonated at the nitrogen atom of the dihy
droisoquinoline moiety. The LH+ cations and [Cu(NO3)(4)](2-) anions are lin
ked by N-H . . .O hydrogen bonds. Of the four nitrate groups, one is coordi
nated monodentate, one is bidentate, and two are anisobidentate.
