G. Ibrahim et al., Metallic complexes from 2-furaldehyde semicarbazone and 5-methyl-(2-furaldehyde) semicarbazone, TRANSIT MET, 24(3), 1999, pp. 294-298
The synthesis and characterization of Co-II, Ni-II, Cu-II and Cd-II complex
es with 2-furfuralsemicarbazone (FSC) and 5-methyl 2-furfuralsemicarbazone
(MFSC) are reported. These ligands lead to the complexes: [ML2X2] or [MLX2]
(L = FSC or MFSC) whose structures were determined using elemental analysi
s, molar conductivity, magnetic measurements, i.r., far i.r. and electronic
spectra as well as by n.m.r. FSC and MFSC act as bidentate ligands in most
of the Co-II, Ni-II, Cu-II and Cd-II complexes. MFSC is a monodentate liga
nd in [NiBr2(MFSC)(4)].
