| Summary: | 碩士 === 中原大學 === 化學研究所 === 100 === This thesis discusses the synthesis and structures of six new metal – organic frameworks containing D,L – camphorate(D,L-camph) and dipyridyl amide ligands. The solventhermal reactions of these ligands with Co(II) salts afforded six complexes of [Co2(D-camph)2(L1)]•2H2O (1), [Co2(D-camph)2 (L2)] •2H2O (2), [Co2(L-camph)2(L2)]•2H2O (3), [Co2(D,L-camph)2(L2)]•2H2O (4), Co2(D-camph)2(L3) (5) and Co(D-camph)(L4) (6). All the complexes have been characterized by EA, IR, UV-vis, TGA, power X-ray diffraction and single crystal X-ray diffraction.
Complex 1 shows the (486108) roa topology, which involves four six-membered rings ( 1 + 3 ) with 3D self-penetrating net. Although L3 is longer then L2, complexes 2 - 5 have the same (41263) pcu topology. The chiral layer formed by camphorate ligand are important in determining the structural type. Complex 6 shows the 2D → 2D 3-fold interpenetration, with the (4)(4•85) topology for the net.
