Notes:
The two title compounds are two-dimensional magnetic systems with ferromagnetic interlayer exchange coupling. Magnetic susceptibility measurements ferromagnetic interlayer exchange coupling. Magnetic susceptibility measurements yield J/k=4.59 and 13.0 K for the two compounds, respectively. A smooth correlation between J and the intralayer Cu-Cu distance is observed. The latter compound orders at TN∼8 K, while no evidence for long-range order in the former is observed down to 1.4 K. The electron paramagnetic resonance linewidths of (C6H5CH2C4H11N2Cl)2CuCl4 are abnormally large with a dominant cos2 θ angular dependence. The assumption that the linewidths are dominated by spin anisotropies leads to an estimate of ||dz/J||(approximately-equal-to)0.14.
