摘要：

The molecular metals BET2[MCl4] with M = Fe, Ga (see article title for BET) have been prepared and their structural, transport, and magnetic properties investigated. It is shown that the conducting layers of the organic donor BET are interleaved by the inorganic ions, which are fairly well isolated from each other in the crystal. However, in the case of the Fe, the ions are found not to be magnetically isolated but coupled by exchange interactions. A mechanism is suggested to account for the observed Fe-Fe interaction in this magnetic molecular metal.
