Heteronuclear multiple bonding between heavier group 14 and 16 elements. A new class of germylated compounds, the germanethiocarbamyl and germaneselenocarbamyl chlorides L2(Cl)GeY (Y = S, Se)

The first monomeric germanethiocarbamyl halides containing a chelating β-diiminate ligand, L2(Cl)Ge=Y (L2 = PhNC(Me)CHC(Me)NPh; Y = S (2), Y = Se (3)), have been prepared by the reaction of the corresponding heteroleptic halogermylene L2(Cl)Ge (1) with elemental sulfur or black selenium in refluxing toluene. Single-crystal X-ray structural analyses of 2 and 3 reveal that the germanium centers reside in highly distorted tetrahedral environments in these compounds; short Ge-Y distances (Ge-S = 2.07 A (2); Ge-Se = 2.21 A (3)) are indicative of an unsaturated character of these germanium-chalcogen bonds. Selective reactions between 2 or 3 and MeLi afforded the corresponding alkylated germanechalco-genones L2(Me)Ge=Y (Y = S (4), Se (5)).

Three coordinate divalent Group 14 element compounds with a β-diketiminate as supporting ligand L2MX [L2=PhNC(Me)CHC(Me)NPh, X=Cl, I; M=Ge, Sn]

The new heteroleptic divalent germanium and tin compounds L2MX [L2=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 L2M+ or may be replaced by other groups after nucleophilic substitution giving L2MR compounds [R=N(SiMe3)2; M=Ge, Sn. M=Sn; R=OSO2CF3, N3]. Reactions of 1 and 2 with elemental S8, Se or transition metal complexes M′(CO)5·THF have resulted in the isolation of the new complexes L2(Cl)ME (E=S; M=Ge, Sn. E=Se, M=Ge) and L2(Cl)MM′(CO)5 (M′=Cr, W; M=Ge, Sn).
