    Description / Table of Contents: Metal Complexes with Anionic Ligands of Elements of the Main Group IV. IV. Homogenous and Heterogenous Transition Metal Complexes of the Dichlorobromo-, Dibromochloro-, and Tribromostannide LigandsMonosubstituted complexes of the type [M(CO)5SnBr3-nCln]- are formed if the hexacarbonyls of chromium, molybdenum, and tungsten are reacted with halogenostannide ions SnBr3-nCln- (n = 0, 1, 2). The reactions of dibenzene chromium and this stannide ions yield homogenous hexakis(trihalogenostannide)chromate(0) complexes [Cr(SnBr3-nCln)6]6- (n = 1, 2). Both types of chromate(0) ions are isolated as salts with the cation [N(C2H5)4]+. The behaviour of SnBr3-nCln- (n = 0-3) as ligands is discussed, the i. r. spectra of their metalcarbonyl derivatives are reported.
    Notes: SnBr3-nCln--Ionen (n = 0-2) reagieren mit den Hexacarbonylen von Chrom, Molybdän und Wolfram zu den anionischen Monosubstitutionsprodukten [M(CO)5SnBR3-nCln]-. Sie warden den analogen Trichlorstannido-carbonylmetallat(0)-Komplexen gegenübergestellt. Die homogenen Hexakis(halogenstannido)-chromat(0)- Komplexe [Cr(SnBr3-nCln)]6- (n = 1, 2) bilden sich als Tetraäthylammoniumsalze bei den Umsetzungen mit Dibenzolchrom. Das komplexchemische Verhalten von Trihalogenstannido-Liganden wird diskutiert, die Infrarot-Spektren warden mitgeteilt.
