Structure and Nature of Bonding of [C₂H₅SFe(CO)₃]₂

The structure of 2,2'-dimercaptodiethylsulphidenickel(II). A dimeric molecule containing bridging sulphur atoms

“…The lengths of the two sets of bonds from the bridging sulphur atoms (2.18 and 2.22/~,) are comparable with the length 2-20 A reported (Woodward, Dahl, Abel & Crosse, 1965) for the Ni-S bonds from the bridging thiol sulphur atoms in the cyclic hexamer (Thomas, Robertson & Cox, 1958), and [C/HsSFe(CO)3]2, 68.3 o (Dahl & Chin-Hsuan Wei, 1963.…”

“…To explain this fact, electron pairing in metal-metal bonds was postulated for these compounds. Dahl & Chin-Hsuan Wei (1963), determined the structure of one of these diamagnetic compounds, [C2HsSFe(CO)3]2, and showed that the molecular geometry was consistent with a bent metal-metal bond [ Fig. 4(a)].…”

“…Thiol ligands, in most cases, give polymeric complexes as a result of the formation of very stable bridges by the sulphur atoms. Further interest in the structure of this molecule lies in the configuration of the nickel and sulphur atoms; Harley-Mason considered them to be coplanar, but X-ray structure analyses of several thioloiron carbonyl complexes containing sulphur bridges (Dahl & Chin-Hsuan Wei, 1963 plex in a mixture of chloroform and ethanol. Small, very dark red plates were formed.…”

“…Les distances moyennes Fe-Fe et Fe--S, ainsi que les angles Fe-S-Fe [moyenne: 68,8 (0,2) ° pour les deux mol6cules] sont en bon accord avee les valeurs correspondantes obtenues dans des d6riv6s binuel6aires du fer carbonyle/l liaison m&al-m&al pont6e par deux atomes de soufre (Dahl & Wei, 1963;Weber & Bryan, 1967;Coleman, Wojeieki, Polliek & Dahl, 1967), et eeci bien que dans la pr6sente structure il y ait un seul atome de soufre ponteur, l'autre pont &ant constitu6 par deux atomes de earbone li6s de mani6re dissym&rique aux atomes de fer. Dans la structure de CsH4N(CO)6Fe2-~aS-Fe2(CO)6SCsH4N (Le Borgne & Grandjean, 1975) (Churchill & Kalra, 1973).…”

The Structure of Derivatives of [SCH3Fe(CO)3]2

“…spectra of these compounds showed that isomer A contained inequivalent or anti sulfur-methyl groups and isomer B contained equivalent or syn sulfurmethyl groups. Later an X-ray crystallographic study of the anti isomer of [SC,H,Fe(CO),], provided more details of the structure of these compounds (2). We have investigated the reactions of [SCH,Fe(CO),j, with tertiary and ditertiary phosphines and assigned structures to the products on the basis of their infrared, proton magnetic resonance (p.m.r.…”
