Synthesis, crystal structure and magnetic properties of [Cu{C[C(CN)(2)](3)}
(en)(2)](n). which arises from reaction of Cu(II) with the highly conjugate
d polynitrile C10N62- ligand ( C10N62- = [C{C(CN)(2)}(3)](2-)) in presence
of ethylenediamine (en = NH2CH2CH2NH2), are reported. This compound present
s a polymeric structure of pseudo-octahedral copper(II) ions bridged by the
polynitrile unit C10N62- The magnetic susceptibility data in the 5-300 K r
ange can be analysed by a Curie law with C = 0.43 cm(3).K.mol(-1).
