Oxomolybdenum monodithiolene complexes linked with sulfur bridged iron: antiferromagnetically coupled Fe(iii)Mo(v) systems

Mo–Fe heterometallic complexes with Fe(X)2 (X = Cl, SPh) moiety attached to monodithiolene oxomolybdenum via sulfur bridge, viz., [Ph4P]2[Cl2FeS2MoOS2(DMED)] (2) (DMED, dimethylethylenedicarboxylate), [Ph4P]2[Cl2FeS2MoO(tdt)] (3) (tdt, toluenedithiolate) and [Ph4P]2[(SPh)2FeS2MoO(tdt)] (4) are reported. Mossbauer spectroscopy, magnetism, EPR, electrochemistry and electronic structure based on DFT and TD-DFT calculation show the transfer of...
