Abstract
Copper(II) complexes have been prepared with 2-isopropylaminopyridine N-oxide (IP) employing the perchlorate, tetrafluoroborate, nitrate, chloride and bromide salts. Preparative molar ratios of 4:1 and 2:1 ligand to copper(II) salt yielded the following unique salts: Cu(IP)4X2(X=ClO4−, BF4−), Cu(IP)3(NO3)2 and Cu(IP)2X2(X=NO3−, Cl− and Br−). Characterization and has been accomplished by infrared, electronic and electron spin resonance measurements primarily of the solid state. IP bonds as a monodentate ligand via its N-oxide oxygen in the first three complexes, but apparently as a bidentate ligand in the latter three. Cu(IP)2(NO3)2 is binuclear and anion coordination occurs in both of the nitrate complexes as well as both halogen solids.
