Iron pentacarbonyl as a precursor for molecule-based magnets: Formation of Fe[TCNE](2) (T-c=100 K) and Fe[TCNQ](2) (T-c=35 K) magnets
The reaction of tetracyanoethylene (TCNE) and 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) with Fe(CO)(5) leads to formation of magnetically ordered materials of Fe[TCNE](2) (T-c = 100 K) and Fe[TCNQ](2) (T-c = 35 K) composition, respectively. In contrast, the reaction with 1,2-dichloro-5,6-dicyanobenzoquinone (DDQ) leads to a paramagnetic material.
