Abstract :
The synthesis of the dithiol precursor of the new ligand 4-cyanobenzene-1,2-dithiolate (cbdt) is described. The (n-Bu4N)[Fe(cbdt)2] complex, was prepared and characterised by X-ray diffraction, Mössbauer spectroscopy and magnetisation measurements. The crystal structure consists in cis [Fe(cbdt)2]- units dimerised in a trans fashion, with Fe in a square pyramidal coordination, the dimers being well isolated from each other by the cations. The magnetic susceptibility shows that the [Fe(cbdt)2]− units have a S = 3/2 spin configuration.
