英文摘要 | Several crystalline germanium oligomers Ge�aO .L�砥DxH�烙(L=amino acid or amine) have been prepared and characterized by IR and NMR spectra, EA (elemental analysis), TGA (thermogravimetric analysis) and ICP-AES (inductively coupled plasma-atomic emission spectroscopy). Oligomers of this type are based on chains of germanium-oxygen single and double bonds and synthesized in aqueous solution from germanium dioxide and basic ligands having an amino group. Two basic amino acids and mono-, and bidentate amines chosen as ligands to react with germanium dioxide gave L-lysine germanate (1a,1b,1c),L-arginine germanate (2a, 2b,2c), Cyclohexylammonium hexagermanate (3), N-methylcyclohexylam-monium hexagermanate (4) , N, N-dimethylcyclohexylammonium hexagermanate (5) , 2-aminoethylam-monium trigermanate (6), 2-(N'-methylamino)-N-methylethylammonium pentagermanate (7) , 2-(N'N'-dimethylamino) -N, N-dimethylethylammonium heptagermanate (8). |
