| Miêu tả: | Germanium(II) compounds featuring β-diketiminate-type ligands are attractive for applications as nanoparticle precursors, imaging agents, and components of electronic devices. In this work, we report the synthesis of β-diketiminatogermanium(II) amides LGe(NHPh) [1, L = {HC(CMeN–2,4,6-Me3C6H2)2} – ], LGe(4-NHPy) (2), LGe(2-NHPy) (3), and LGe(2-NHPy) (4), L = {HC(CMeN–2,6-iPr2C6H3)2} – ], which were obtained by the reaction of a low-valent organogermanium halide (LGeCl or LGeCl) with a lithium salt of the respective aromatic amine (LiNHPh) or aminopyridine [Li(4-NHPy) and Li(2-NHPy)]. Compounds 1–4 were characterized with several techniques such as melting point, FTIR, 1H and 13C NMR spectroscopy, elemental analysis, X-ray diffraction, and thermogravimetric analysis (TGA). Compounds 1–3 and 4 crystallized in the orthorhombic (space group Pnma) and monoclinic (space group P21/c) crystal systems, respectively. In all cases, the geometry around the central germanium atom was highly tetrahedrally distorted. According to TGA data, 1–4 do not sublime intact but rather exhibit thermal decomposition. |
