Two novel oxomolybdenum complexes derived from the reaction of chlorotrisulfidomolybdate precursor with a pyridine-containing tridentate ligand

► In the anion, [MoClS3]−, both the chloride and sulfide are readily replaced by a tridentate ligand. ► The reaction led to forming two complexes, one mononuclear and one dinuclear. ► The dinuclear complex possesses a core of {Mo(v)Mo(v)}.
