博士 === 國立清華大學 === 化學系 === 90 === This thesis describes 17 new gallophosphates and transition metal substituted gallophosphates, which were synthesized by hydrothermal reaction. All compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, EPMA, ICP-AES, solid-state NMR spectroscopy, and magnetic susceptibility data. These compounds were divided into three parts by different template or structure directing agent: The first system: DACH/(M, Ga)/P/O (M= Zn) was contributed by three compounds. There are the two dimensional layer-structure of (1S,2S)-H2DACH][Ga2(1S,2S-DACH)(HPO4)(PO4)2] (1), novel three dimensional structure of (H2DACH)2[Zn4Ga2(HPO4)3(PO4)4] (2), and CGS topology of (H2DACH)[Zn2Ga2(PO4)4] (3). The second system: PPZ/(M, Ga)/P/O (M = Ti, Zn) was contributed by five compounds. There are the one dimensional chain-structure of (H2PPZ)3[Ga4(OH)2(PO4)2(HPO4)4(H2PO4)2] (4), the same widen layer structure of (H2PPZ)3[Ga8(H2O)4(PO4)10]×2H2O (5) and (H2PPZ)3[TixGa8-x(H2O)4(PO4)10]×2H2O (x~2.52) (6), SOD topology of (H2PPZ)[Zn2Ga(PO4)3] (7), and GIS topology of (H2PPZ)[Zn2Ga2(PO4)4]·H2O (8). The third system: DIEN/(M, Ga)/P/O (M = Cr, Mn, Fe, Co, Zn) was contributed by nine compounds. There are the three dimensional framework of [Ga2(DETA)(PO4)2]·2H2O (9) with one dimensional 24-membered ring, the chromium substituted [CrxGa1-x(DETA)(PO4)2]·yH2O (x~0.17, y~0.95) (10), the cobalt substituted [CoxGa1-x(DETA)(PO4)2]·yH2O (x~0.11, y~0.86) (11)，the chromium and cobalt substituted [CoxCryGa1-x-y(DETA)(PO4)2]·zH2O (x~0.19, y~0.21, z~1.02) (12)，the manganese substituted [MnxGa1-x(DETA)(PO4)2]·yH2O (x~0.2, y~1.33) (13)，the iron substituted [FexGa1-x(DETA)(PO4)2]·yH2O (x~0.2, y~1.11) (14), the zinc substituted [ZnxGa1-x(DETA)(PO4)2]·yH2O (x~0.17, y~1.17) (15), and 3D chiral framework of (H3DETA)[Mn(H2O)2Ga(PO4)2]3 (16) and (H3DETA)[Zn3Ga(PO4)4]·H2O (17).
