INDIUM MONOHALIDE INSERTION REACTIONS INTO METAL-METAL BONDS - CRYSTAL-STRUCTURE OF [INCL(THF)(MO(CO)3(ETA-C5H5))2]

The reaction between InCl and [Mo2(CO)6(η-C5H5)2] affords [InCl&{;Mo(CO)3(η-C5H5)&};], 6a which has been characterised as a THF adduct [InCl(THF)&{;Mo(CO)3(η-C5H5)&};2], 10, by X-ray crystallography. An additional complex, [InCl2&{;Mo(CO)3(η-C5H5)&};2]-, 11, is also formed in this reaction. Similar products are reported for reactions involving [M2(CO)6(η-C5H5)2] (M = Cr, W). The reaction between InCl and [Fe2(CO)4(η-C5H5)2] affords [InCl{Fe(CO)2(η-C5H5)}2], 17, and [InCl2{Fe(CO)2(η-C5H5)}], whilst that between InI and [Fe2(CO)4(η-C5H5)2] affords [InI{Fe(CO)2(η-C5H5)}2], 19. © 1990.
