STRUCTURAL, MAGNETIC AND SPECTROSCOPIC CHARACTERISATION OF BIS-(BENZIMIDAZOLE) TETRAKIS-(μ-ACETATO)DICOPPER(II)
TLDR
In this article, the complex bis-(benzimidazole)tetrakis-(μ-acetato)dicopper(II) has been investigated by spectroscopic and magnetic methods.Abstract:
The complex bis-(benzimidazole)tetrakis-(μ-acetato)dicopper(II) has been investigated by spectroscopic and magnetic methods. Variable-temperature (77–290K) magnetic measurements indicate a strong antiferromagnetic interaction between the copper (Cu2+) paramagnetic centres. The exchange parameter, J. was found to be −162 cm−1, by least-squares fitting to the spin Hamiltonian H=−2JS1.S2. The EPR spectrum of a polycrystalline sample of the complex revealed triplet state (S=1) transitions and the D and E zero-field splitting parameters, equal to 0.354 and 0.0032 cm−1, respectively.read more

Anomalous Paramagnetism of Copper Acetate
Brebis Bleaney,K. D. Bowers +1 more
TL;DR: In this article, the paramagnetic resonance spectrum of copper acetate is anomalous in that it resembles that of an ion of spin 1, and its intensity decreases as the temperature is lowered.
