Synthesis, characterization, and properties of the first indium borogermanate incorporating an organic amine ligand: InBGe2O6(OH)2(CH3CH(NH2)CH2NH2)·2H2O

A new indium borogermanate incorporating an organic amine ligand, InBGe2O6(OH)2(CH3CH(NH2)CH2NH2)·2H2O, was synthesized under solvothermal conditions and characterized by infrared spectroscopy, thermogravimetric analysis, and emission spectroscopy. This compound is a new example of the combination of metal, boron, and germanium atoms into one structure in the presence of organic amine molecules. Its 2D sheets with one 3-, one 4-, and two types of 6-membered rings consist of In2O6N4 octahedral dimers, Ge2O6(OH) double tetrahedra, and BO3(OH) groups that are interconnected by water molecules to form a 3D supramolecular framework. Interestingly, the emission spectrum for this compound displays a strong broad band centered at 455 nm.

The first example of indium borogermanate incorporating an organic amine ligand was synthesized under solvothermal conditions. Infrared spectroscopy, thermogravimetric analysis, and emission spectroscopy have also been studied.Figure optionsDownload as PowerPoint slide
