Formation of Metal-Clusters or Nitrogen-Bridged Adducts by Reaction of a bis(Amino)Stannylene with Halides of 2-Valent Transition-Metals
When the cyclic bis(amino)stannylene Me(2)Si(NtBu)(2)Sn is allowed to react with metal halides MX(2) (M = Cr, Fe, Co, Zn; X = Cl, Br [Zn]) adducts of the general formula [Me(2)Si(NtBu)(2)Sn . MX(2)](n) are obtained. The compounds are generally dimeric (n 2) except the ZnBr2 adduct, which is monomeric in benzene. The crystal structures of [Me(2)Si(NtBu)(2)Sn . CoCl2](2) (triclinic, space group <(P)over bar 1>; a = 8.620(9) Angstrom, b = 9.160(9) Angstrom, c = 12.280(9) Angstrom, alpha = 101.2(1)degrees, beta = 97.6(1)degrees, gamma = 105.9(1)degrees, Z = 1) and of [Me(2)Si(NtBu)(2)Sn . ZnCl2](2) (monoclinic, space group P2(1)/c; a = 8.156(9) Angstrom, b = 16.835(12) Angstrom, c = 13.206(9) Angstrom, beta = 94.27(6)degrees, Z = 2) were determined by X-ray diffraction techniques.
