摘要:

We report the synthesis and physical properties of compounds of BEDT-TTF with transition metal tris-oxalate anions. The crystal structure of one such compound, (BEDT- T TF)4KFe(C2O4)3C6H5CN (1) has been determined. The structure consists of alternating layers of BEDT-TTF and a hexagonal network of K+and Fe(C2O4)33-. This material is a semiconductor with an activation energy of 0.14eV. Magnetic data obey the Curie-Weiss law with C = 4.44 (S=5/2) and O= −0.25K.
