碩士 === 國立中央大學 === 化學研究所 === 99 === There are six novel compounds. The series A denotes organic amine metal-germanate, Zn2Ge4O10(NH2CH2CH2CH2NH2) (A1)、ZnGe2O5(NH2CH2CH2NH2) (A2)、β-In2Ge6O15(NH2CH2CH2NH2)2 (A3) and γ-In2Ge6O15(NH2CH2CH2NH2)2 (A4). The series B denotes zinc-organogermanate, ZnE2Ge2O3 (B1) and Zn2EGeO3 (B2). All structures are determined by single-crystal X-ray diffraction, and the details of these structures are discussed. The purity of each compound was confirmed by thepowder X-ray diffraction analysis, and the properties of these compounds were further characterized by different instrumental measurements, such as element analysis, infrared spectra analysis, and thermogravimetric analysis. The A series were synthesized under solvothermal conditions by choosing different metals and organic amines to form organic amine metal-germanate. Compound A1 and A2 used organic animes as solvents, while compound A3 and A4 used 2-methylpentamethylenediamine as solvent. A1 strucutre is characterized by infinite chain formed of edge-sharing ZnO4N trigonal bipyramds and [Ge4O10] layers to form 3D framework. A2 strucutre is characterized by ZnO2N2 tetrahedra and [Ge2O5] chains to form 3D framework. A3 and A4 are polymorphs. Their strucutres are characterized by In2O6N4 dimers and germanates layers to form 3D framework. The B series were synthesized hydrothermal conditions by choosing zinc metal and organogermanate to form zinc-organogermanate. B1 structure is characterized by E goups linked to germanate layers and ZnO4 tetrahedra into 3D framework. B2 structure is characterized by E groups linked to mixed metal layers into 3D framework.
