Following our investigations into the complexing properties of 5-substituted 2-furfuraldoximes, we describe here the first complexes obtained from 5-nitro-2-furfuraldoxime (5-NO2-FDH or L) and 3d element dihalides, formulated as [ML2X2], [ML3X2] and [ML4X2] (M = Co, Ni or Cu; X = Cl or Br). The structures are discussed on the basis of analytical, i.r. spectral data and thermal analysis.
