文摘

Two open-framework germanates, SUT-1 and SUT-2, have been synthesized under hydrothermal conditions using ethylenediamine (en, H₂NCH₂CH₂NH₂) as templates and Ni(NO₃)₂路6H₂O as the transition-metal source. Their frameworks are built with Ge₁₀ clusters and [Ni(en)₂]²⁺ complexes. In both structures, Ge₁₀ clusters form square nets in the a鈥?i>c plane, while the [Ni(en)₂]²⁺ complexes bridge the square nets via Ni鈥揙鈥揋e bonds to form 3D networks. They present the first examples to incorporate Ni²⁺ complexes into the germanate frameworks. In SUT-2, additional linkages by Ge₂O₇ clusters between the square nets generate a new type of topology.
