title: A borogermanate with three-dimensional open-framework layers.
abstract: A layered borogermanate with three-dimensional microporosity within the layers, K(4)[B(8)Ge(2)O(17)(OH)(2)] (monoclinic, space group: C2/c; a=12.095(2), b=6.7979(14), c=19.944(4) A; beta=93.04(3) degrees ; V=1637.6(6) A(3); Z=4), has been synthesized in a flux of potassium borate. Because of its three-dimensional pore structure and thermal stability, the compound has the potential to eventually form nanocomposites with polymers and to be processed into thin microporous films.
