TL;DR: The coordination chemistry of pyridine N-oxide with a variety of acceptors has been investigated in this article, where the new substances Co(ClO4)26L, Co(NO3)24L), CoCl23L and CoCl2LH20, NiClO 4H2O, NiBr26L and NiBr2L H2O have been isolated and characterized by molecular conductance measurements in non-aqueous solvents, magnetic susceptibility measurements, and infrared spectra.
Abstract: : The coordination chemistry of pyridine N-oxide with a variety of acceptors has been investigated The new substances Co(ClO4)26L, Co(NO3)26L, CoCl23L, CoCl2LH20, Ni(ClO4)26L, NiCl2LH2O, NiBr26L, NiI26L, NiBr2L H2O, Cu(ClO4)24L, Cu(NO3)22L, CuCl2L, CuCl22L, Zn(ClO4)26L, ZnCl22L, Zn(NO3)26L, Fe(ClO4)26L, Fe(ClO4)36L, and SnBr42L (where L is pyridine N-oxide) have been isolated and characterized by molecular conductance measurements in non-aqueous solvents, magnetic susceptibility measurements, and infrared spectra All of the perchlorates and some of the nitrates and halides have only the pyridine N-oxide in the first coordination sphere However, in some cases, both nitrates and halides are coordinated to the central ion
