Magnetic susceptibility study of copper(II) halide complexes with 4-substituted pyridine N-oxides

Article abstract of DOI:10.1021/ic50079a016

The magnetic susceptibilities have been measured for 12 1:1 copper(II) halide complexes with 4-substituted pyridine N-oxides from 77°K to near the melting or decomposition temperatures. The magnetic susceptibility data were least-squares fitted to a modified Bleaney-Bowers equation. The correlations of the exchange energy, 2J, with the reflectance spectra and the substituent parameter σ_R are discussed in terms of the molecular and crystal structures.
