Abstract

New charge-transfer salts (ET)8(MnBr4) 2(DCE)2 1 and (ET)3MnBr4 2 have been synthesized electrochemically and characterized. In both compounds the magnetic MnBr42- onions exist separately between the conducting ET-layers. The shortest intermolecular Mn⋯Mn distances are 7.28 and 10.12Å, respectively, which are too far to magnetically interact directly. But magnetic susceptibility measurements demonstrated that the antiferromagnetic interactions was observed at low temperature. This aniferromagnetic interactions between Mn ions may be operative via the π-electrons of conducting layers, that are so-called d-π interactions. The crystal structures and physical properties of these compounds are reported.
