The Donor Properties of Pyridine-N Oxide
Abstract:
The coordination chemistry of pyridine N-oxide with a variety of acceptors has been investigated. The new substances CoClO42.6L, CoNO32.6L, CoCl2.3L, CoCl2.L.H20, NiClO42.6L, NiCl2.L.H2O, NiBr2.6L, NiI2.6L, NiBr2.L. H2O, CuClO42.4L, CuNO32.2L, CuCl2.L, CuCl2.2L, ZnClO42.6L, ZnCl2.2L, ZnNO32.6L, FeClO42.6L, FeClO43.6L, and SnBr4.2L 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.
