The family of molecular dianions [S2WS2Fe(NCS)(X)]2-(X=Cl-,NCS-,N3-orN3-) has been synthesized and characterized by X-ray diffraction, IR, electronic and electrospray mass spectroscopies. This series of compounds was obtained using the lability of the terminal chloro ligands in [S2WS 2FeCl2]2-. A series of thioheterobimetallic anions have been synthesized: [S2WS2Fe(NCS)X]2- (X = Cl- (1); X = NCS- (2); X=N3- (3)). The molecular dianions were isolated by substitution in [S2WS2FeCl 2]2- of the labile terminal chloro ligands by NCS - and/or N3-. Anions (1) and (3) are the first iron tris-heteroleptic complexes of the well-known [S2WS2FeX2] 2- (M = Mo, W) family. The structures of the three molecular anions, isolated as tetraphenylphosphonium salts, are reported, as well as characterization by IR, electronic and electrospray mass spectroscopies.
