Two Open-Framework Germanates with Nickel Complexes Incorporated into the Framework

• Two open-framework germanates, SUT-1 and SUT-2, have been synthesized under hydrothermal conditions using ethylenecliamine (en, H(2)NCH(2)CH(2)NH(2)) as templates and Ni(NO(3))(2)center dot 6H(2)O as the transition-metal source. Their frameworks are built with Gel() clusters and [Ni(en)(2)](2+) complexes. In both structures, Gel clusters form square nets in the a-c plane, while the [Ni(en)2]2+ complexes bridge the square nets via Ni-O-Ge bonds to form 3D networks. They present the first examples to incorporate Ni(2+) complexes into the germanate frameworks. In SUT-2, additional linkages by Ge(2)O(7) clusters between the square nets generate a new type of topology.
