Abstract
Cu(II) complexes have been prepared with N-isopropyl-2-picolinamine N-oxide (IPA) employing the perchlorate, tetrafluoroborate, nitrate, chloride and bromide salts. Preparative molar ratios of 4:1 and 2:1 ligand to Cu(II) salt yielded the following unique solids: Cu(IPA)2X2(X=ClO4−, BF4− and NO3−) and Cu(IPA)X2(X=Cl, Br). Characterization has been accomplished primarily by IR, electronic and ESR measurements of the solid state. IPA bonds as a bidentate ligand via its N-oxide oxygen and amine nitrogen in all of the complexes. Anion coordination occurs in the halogen complexes and the nitrate ions appear to be bound to Cu(II) as monodentate ligands in Cu(IPA)2(NO3)2.
