Beschreibungen/Notizen

• The title compound (abbreviated as MPzATSH) has been synthesised and physico-chemically (IR, PMR and mass spectrum) characterised for the first time. The ligational behaviour of the thiosemicarbazone has been demonstrated by isolation and characterisation of its complex species with Co(III), Ni(II) and Cu(II) with different counterions. Magnetic and spectral features indicate Co(MPzATS) 2X (X = Cl, Br, ClO 4, BF 4, NO 3 or 1 2 SO 4) as the diamagnetic octahedral species with the ligand in the deprotonated thiol form, while Ni(MPzATSH) 2X 2 and Cu(MPzATSH)X 2 are proposed as octahedral complexes with the ligand in the neutral “thione” form.
