New molecule based magnetic materials [CrCyclam(CC-MeEDT-TTF) 2 ](TCNQ) 3 ([1](TCNQ) 3 , Cyclam=1,4,8,11-tetraazacyclotetradecane, MeEDT-TTF=5-methyl-4′,5′-ethylenedithiotetrathiafulvalene, TCNQ=7,7,8,8-tetracyanoquinodimethane) and [1][Cr(NCS) 4 Phen] 2 (acetone) 2 (toluene) (Phen=1,10-phenanthroline) were prepared by the electrochemical oxidation of [1](CF 3 SO 3 ). Tetrathiafulvalene(TTF)-type ligands and a neutral TCNQ molecule are stacked and form a charge-transfer complex in the crystal of [1](TCNQ) 3 , where a weak ferromagnetic interaction was observed between Cr 3+ and (TCNQ) 2 − . The crystal structure of [1][Cr(NCS) 4 Phen] 2 (acetone) 2 (toluene) was characterized by ferrimagnetic chain of Cr 3+ Cyclam units (S=3/2) and (TTF) 2 + ligand dimers (S=1/2), while each (TTF) 2 + dimer is sandwiched between two [Cr(NCS) 4 Phen] − anions (S=3/2). The crystal shows ferrimagnetic transition at 4.8K.
