Ethylenediamine (en)ranks high in the spectrochemical series and produces a strong crystal field in complex ions [Co(en)] . Based on this information, (1) write the electron configuration of Co (III) (2) what is the geometry structure of this complex ion? Linear, Tetrahedral, Square planar or Octahedral. (3) predict the number of unpaired electrons in [Co(en) ] (4) draw the crystal field diagram for this complex ion Using t2g and eg.
