Abstract

Mean field expressions based on the simple Heisenberg model were derived to correlate the intra-and interlayer exchange couplings to the critical temperatures, T_c, for three metallocyanide-based magnets with extended 2-and 3-D structure types. These expressions were used to estimate the exchange coupling, J, for 2-D ferrimagnetic [NEt₄]₂Mn ^II₃(CN)₈, 3-D antiferromagnetic [NEt ₄]Mn^II₃(CN)₇, and 3-D antiferromagnetic interpenetrating 3-D Mn^II(CN)₂. The type and magnitude of the exchange coupling are in accord with the previously reported magnetic data.
