Resumen

Ferrimagnetic coupling in a mesogen is reported for the first time for the compound Mn-III[((OC12H25)(4)TPP)](TCNE) . 2 toluene (where TPP = tetraphenyl porphyrin, TCNE = tetracyanoethylene), which displays liquid crystal properties above 381 K and ferrimagnetic properties below 21.4 K. The results from differential scanning calorimetry, X-ray diffraction, and AC susceptibility studies are discussed. Evidence is presented for the presence of net magnetic moments at zero applied field.
