Summary
Copper(II) complexes of 2-amino-3-picolineN-oxide (3 MA) have been isolated as perchlorate, tetrafluoroborate, nitrate, chloride and bromide salts, and characterized by spectral methods (i.e., i.r., u.v.-vis and e.s.r.). Variation of the ligand to copper(II) salt ratio yielded solids having the following empirical formulas: Cu(3 MA)4X2 (X = ClO4, BF4 or NO3), Cu(3 MA)2X2 (X = NO3, Cl or Br) and Cu(3 MA)X2 (X = Cl). In addition, a deprotonated ligand complex, Cu(3 MA-H)2, was prepared by treating an aqueous slurry of Cu(3 MA)4(ClO4)2 with NaOH. This complex is considered to be square planar, but does associate to form a dimer in nonpolar solvents such as CHCl3. The complexes involving coordinated anions appear to be polymeric and to contain halogen orN-oxide oxygen bridging ligands.
