Metal Complexes with Anionic Ligands of Elements of the Main Group IV. VIII Pentacarbonyltrihalogenostannidometalate(O) Complexes of Chromium, Molybdenum, and Tungsten with Fluorine and Iodine Containing Trihalogenostannido LigandsIn methylenechloride [As(C6H5)4][SnF3] readily reacts with the metalhexacarbonyls forming the arsoniumsalts of the pentacarbonyltrifluorostannidometalate(O) complexes, [M(CO)5SnF3]- (M = Cr, Mo, W). Exclusively by the reaction of the intermediately formed complex Cr(CO)5THF only one pure triiodostannidometalate(O) Complex, [N(C2H5)4][Cr(CO)5SnJ3], could be isolated. The trihalogenostannidometalate(O) complexes [M(CO)5SnClX2]- (X = F: M = Cr, Mo, W; X = J: M = Cr) could be prepared by SnX2-insertion reactions of the [M(CO)5Cl]- complexes. The bonding properties of the halogenostannide ions are discussed on the bases of the IR spectra of their metalate(O) complexes.
Notes:
In Methylenchlorid setzt sich [As(C6H5)4][SnF3] glatt mit den Metallhexacarbonylen zu den Arsoniumsalzen der Pentacarbonyl-trifluorstannido-metallat(O)-Komplexe [M(CO)5SnF3]- (M = Cr, Mo, W) um. Mit [N(C2H5)4][SnJ3] konnte in THF-Lösung nur über das Zwischenprodukt Cr(CO)5 THF ein Trijodstannidochromat(O)-Komplex [N(C2H5)5][Cr(CO)5SnJ3] rein erhalten werden. Durch SnF2-bzw. SnJ2-Insertionsreaktionen an den [M(CO)5Cl]--Komplexen erhält man die Trihalogenstannidometallat(O)-Komplexe [M(CO)5SnClX2]- (X = F: M = Cr, Mo, W; X = J: M = Cr). Anhand der IR-Spektren wird das Bindungsverhalten halogenhaltiger Stannid-Ionen diskutiert.
