摘要:
The new heteroleptic divalent germanium and tin compounds (LMX)-M-2 [L-2 = PhNC(Me)CHC(Me)NPh. X = Cl; M = Ge (1), Sn (2). X = I; M = Ge (3), Sn (4)] have been synthesized and physicochemically and structurally (2) characterized. The halide ligand of all compounds can either be removed by reaction with NaBPh4 leading to the cationic Ge(II) and Sn(II) species (LM+)-M-2 or may be replaced by other groups after nucleophilic substitution giving (LMR)-M-2 compounds [R = N(SiMe3)(2); M = Ge, Sn. M = Sn; R = OSO2CF3, N-3]. Reactions of 1 and 2 with elemental S-8, Se or transition metal complexes M ' (CO)(5) THF have resulted in the isolation of the new complexes L-2(Cl)ME (E = S; M = Ge, Sn. E = Se, M = Ge) and L-2(Cl)MM ' (CO)(5) (M ' = Cr, W; M = Ge, Sn). (C) 2001 Elsevier Science B.V. All rights reserved.
