Abstract

The syntheses and structures of heteroleptic germanium(II) and tin(II) chlorides supported by anionic ligands derived from 2,3-dimethyl-1,4-diaza-1,3- butadiene are described. The reaction of ArN=C(Me)C(Me)=NAr (L, Ar = 2,6-iPr₂C₆H₃) with MeLi in Et₂O, followed by treatment with GeCl₂·dioxane or SnCl₂, afforded [L¹ECl] [L¹ = ArN=C(Me)C(Me)₂NAr; E = Ge (1), Sn (2)]. Moreover, L²Li [L² = ArN=C(Me)C(=CH ₂)NAr] reacted with GeCl₂·dioxane in Et ₂O to form [{C(=CH)NAr}{C(Me)=NAr}]₂(GeCl)₂ (3). The byproducts are [{C(CH₂)NAr}{C(Me)=NAr}Ge]₂ (4) and L²H (5). Furthermore, the reaction of L with LiNiPr₂ in Et₂O, followed by treatment with SnCl₂, afforded [L²SnCl] (6). Compounds 1-4 and 6 have been characterized by NMR spectroscopy and X-ray crystallography.
