Abstract
The temperature dependence of the magnetic susceptibility ofA 2MnCl6 salts (A = NH4 +, K+, Rb+) has been measured, and their crystal structures determined using powder X-ray diffraction methods. The structures of these simple cubic salts are governed by thex coordinate of the halide ion. The magnetic and the structural data suggest the presence of antiferromagnetic interactions between adjacent MnCl 2−6 octahedra across bridges of the type as were found in related iridium salts: the susceptibility and the structural data have been used to estimate
separately the values of ratios of the exchange integrals between pairs of salts; the agreement is better than 6 %.
