The monoclinic crystal structure of [NH 3 -(CH 2 ) 2 -NH 3 (CuCl 4 consists of two-dimensional (b, c) layers of square planar (CuCl 4 ) 2- entities, separated from each other by [NH 3 -(CH 2 ) 2 -NH 3 ] 2+ alkylene chain sheets. Electron Paramagnetic

We have studied the EPR of a single crystal of the Tutton salt Cu(NH4)2(SO4)2.6H2O in rotations around the a and c ∗ axes, and around the magnetic β(≡b) and γ axes at X-band and room temperature. When the magnetic field lies in the (a,c) plane,

In the case of rather strong exchange, we have used a method already published by two of us in order to determine for the Rb compound J ′/ k = (0.28±0.03) K. In the case of rather weak exchange, we have used a method proposed by Hoffmann in order

EPR spectra of polycrystalline compounds MnSO4 · (NH4)2SO4 · 6H2O, Gd2(SO4)3 · 8H2O, and NH4Fe(SO4)2 · 12H2O are recorded at X-band and room temperature. For the first two compounds, good agreement with simulated spectra of Gaussian lineshape is

Electron paramagnetic resonance (EPR) experiments on a single crystal of [NH3(CH2)4NH3]CuCl4, with a quasi-bidimensional structure, have been carried out when rotated around a, b and c ∗ axes, at X-band. A careful analysis of experimental dat
