| 中文摘要 | The self-assembly of Ge-O polyhedra by metal-complex templates leads to initial examples of open germanate structures under mild solvothermal conditions. These materials are constructed from Ge-O cluster building bocks (Ge(7)X(19) (X = 0, OH, or F) or Ni@Ge(14)O(24)(OH)(3)) and span the full range of dimensionalities from 1D chains of Ge(7)O(13)(OH)(2)F(3).Cl.2[Ni(dien)(2)] (FJ-6) to 2D layers of Ge(7)O(14)F(3)center dot 0.5[In(dien)(2)]center dot 0.5H(3)dien center dot 2H(2)O (1) and 3D frameworks of Ni@ Ge(14)O(24)(OH)(3)center dot 2[Ni(L)(3)] (FJ-la/FJ-1b) (dien = diethylenetriamine, L=ethylenediamine (en) or 1,2-diaminopropane (enMe)). The Ge(7)X(19) cluster in FJ-6 and I is formed by condensation of four GeX(4) tetrahedra, two GeX(5) trigonal bipyramids, and one GeX(6) octahedron with a mu(3)-O atom at the center of the cluster, whereas the Ni@Ge(14)O(24)(OH)(3) cluster in FJ-1a/FJ-1b is formed by condensation of nine peripheral GeO(4) tetrahedra and five interior GeO(3)Ni units with one mu(5)-Ni atom at the center of the cluster. FJ-6 is characterized by a pair of racemic Ge(7)O(14)(OH)(2)F(3) cluster chains and represents only one example of ID germanates; 1 exhibits unique germanate layers with uniform 10-membered-ring apertures encapsulating an unknown indium complex, and the framework structure of FJ-1a/FJ-1b with large 24-membered-ring channels is the first example of porous materials that contain metal-metal bonds (Ge(2+)-Ni(+)). These initial examples of germanates from metal-complex templates provide a useful model system for understanding the mechanisms of host-guest interactions, which may further facilitate the design and development of new porous materials "on demand". It is shown that the symmetry and configuration of the guest metal complex can be imprinted onto the host inorganic framework through hydrogen bonding between host and guest. |
