摘要：

Isomorphous compounds exhibiting the general formula [M(N-3)(2)(bpa)](n) (M=Mn-II 1, Co-II 2 or Ni-II 3; bpa=1,2-bis(4-pyridyl)ethane) have been prepared and magnetostructurally characterised. X-Ray diffraction analysis revealed a 2-D arrangement of octahedrally co-ordinated metal cations where di-mu-(1,3)-N-3-bridged metallic chains are connected through bpa ligands. IR and UV-VIS spectra were consistent with this structural characterisation. Magnetic analysis carried out by means of ESR spectroscopy and susceptibility measurements indicated that the three compounds are antiferromagnetic, J values being -5.7, -14.0 and -80 cm(-1) for 1, 2 and 3, respectively.
