The reactions of organoiron sulfanes, (μ-Sx)2 (X=3, 4) with acid chlorides, RCOCl, produce the new organoiron thiocarboxylates, FeCp(CO)2SCOR, where R=2-CH3C6H4, I; R=2-CH3COOC6H4, II; R=3,5-(O2N)2C6H3, III; R=2-O2NC6H4, IV and R=2-FC6H4, V.The organoiron thioterephthalate (CO)2CpFeSCOC6H4COSFeCp(CO)2 (VI) has also been prepared.The new complexes were characterized by Ir, 1H NMR and elemental analysis and the crystal structure of complex IV was determined by X-ray diffraction.Complex IV crystallises in the monoclinic system, space group P2₁/c with a 923.9(4), b 1132.2(4), c 1497.6(7) pm; β 106.87(4) deg; d_calc 1.64 g cm^-3; μ 11.3 cm^-1; Z=4; R₁=0.0414 and R²=0.0455.The thiocarboxylate group is bonded to the iron atom through sulfur.
