The cyclo-C3 ligand: Trimetallic cyclopropenium complexes of Group 6-8 metals, including the X-ray crystal structure of [{Fe(CO)2(Cp)}3(μ3-C3)][SbF 6]

, p. 133 - 143 (1999)
Several trimetallic cyclopropenium cations have been prepared via reactions of three equivalents of a metallate anion with [C3Cl3][SbF6]. The X-ray crystal structure of [{Fe(CO)2(Cp)}3(μ3-C3)][SbF 6] (1) shows a nearly equilateral C3 ring with an iron center bonded to each vertex. The cyclopropenium complexes [{Ru(CO)2(Cp)}3(μ3-C3)][SbF 6] (2), [{Mo(CO)3(Cp)}3(μ3-C3)][SbF 6] (3), [{W(CO)3(Cp)}3(μ3-C3)][SbF 6] (4), and [{Re(CO)5}3(μ3-C3)][SbF 6] (5) were spectroscopically characterized. Because of the 3-fold symmetrical nature of these complexes, their NMR spectra display a single cyclo-C3 ring carbon resonance and a single set of resonances for the metal moiety. Compound 1 reacts with Li[BHEt3] and LiMe to give complex reaction mixtures. We were not able to add a fourth metal center to the C3 ring of 1. The spectroscopically characterized C9 complex [{Fe(CO)2(Cp)}3{μ3-C 3(C≡C)3}][SbF6] (6), prepared by the reaction of three equivalents of [Fe(C≡CSiMe3)(CO)2(Cp)] with [C3Cl3][SbF6], was not stable enough to isolate in analytically pure form.

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; dcalc 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.

Stable complexes of general formula CpFe(CO)2SeC(S)OR, where R = Ph (1a), 4-C6H4Cl (1b), 4-C6H4F (1c), C6F5 (1d), 4-C6H4CH 3 (1e), were prepared by the reaction of (μ-Se)[CpFe(CO) 2]2 with ROC(S)Cl at room temperature. When a THF solution of 1 was photolyzed the chelate complexes CpFe(CO)(κ2Se,S- SeC(S)OR) (2) were obtained in good yields. All of these complexes have been characterized by elemental analyses, IR and 1H NMR spectroscopy. The structure of CpFe(CO)2SeC(S)O-4-C6H4Cl (1b) is reported.

A group of dithiocarbonate iron complexes CpFe(CO)2SC(S)OAr (1) were prepared by the reaction of (μ-Sx)[CpFe(CO)2]2 with arylchlorothionoformates (Ar = Ph (1a), 4-C6H4Cl (1b), 4-C6H4F (1c), C6F5 (1d), 4-C6H4CH3 (1e)). The conversion of 1 into CpFe(CO)(κ2S,S-SC(S)OAr) (2), in which the dithiocarbonate ligand is bonded to the iron through the two S-atoms, can be achieved photolytically. The structure of CpFe(CO)2SC(S)O-4-C6H4Cl (1b) is reported.

, p. 812 - 816 (2008/10/08)
A heterobimetallic complex with a CF2 bridge, [CpFeIr(CO)2(PMe2Ph)2(μ-CO)(μ-CF 2)][BF4] (1a), was prepared by the oxidative addition of [CpFe(CO)2(CF2)]+ to Ir(Cl)(CO)(PMe2Ph)2. The [BPh4]- salt of the dimetal compound 1a undergoes a Lewis acid displacement with BCl3 to generate the BCl3 adduct of Ir(Cl)(CO)(PMe2Ph)2 and [CpFe(CO)2(CF2)][BPh4]. The crystal structure of 1a reveals a nearly symmetric CF2 bridge between Fe and Ir, whereas a CO ligand is in a semibridging position between these two metal atoms. Crystal data: monoclinic, space group P21/n, a = 9.308 (2) A?, b = 16.447 (3) A?, c = 20.997 (4) A?, β = 98.69 (2)°; Z = 4; 388 parameters were refined on 4901 reflections with I > 3σ(I) to yield R = 0.036 and Rw = 0.049.
