Abstract

Variable-temperature ⁵⁷Fe Mössbauer measurements on cyanide-bridged 2-D bimetallic assemblies NEt₄[Mn(salen)]₂[Fe(CN)₆] (1), K[Mn(3-MeOsalen)]₂[Fe(CN)₆] (2) and K[Mn(3-MeOsalen)]₂[Fe(CN)₆] · 2 DMF (3), where salen^2- = N,N′-ethylenebis(salicylidene iminato) dianion, revealed that these compounds exhibit a long range magnetic ordering below ca. 10 K under zero applied field. The quadrupole splittings of 1 - 3 showed intermediate values between those of typical cyano-bridged 1-D and 3-D complexes. The paramagnetic state of K[Mn(5-Cl-salen)]₂[Fe(CN)₆] · 4 H₂O (4) turned to a bulk magnetic one with desolvation.
