A novel 3D open-framework germanate, vertical bar N(2)C(4)H(14)vertical bar(4) [Ge(20)O(41)(OH)(6)]center dot 3H(2)O (SU-62), was prepared from hydrothermal synthesis using 1,4-diaminobutane as the organic structure directing agent (SDA). The crystal structure was solved by single crystal X-ray diffraction. The framework is built from Ge(10)(O,OH)(27) (Ge(10)) secondary building units and exhibits an irregular three-dimensional channel system encircled by 10- and 14-rings. The framework of SU-62 has an underlying topology that follows a novel five-coordinated svh-5-I4(1)/amd net, while the pores follow the tsi net. The thermal behavior of SU-62 was studied by thermogravimetric (TG) analysis and in situ X-ray diffraction (XRPD). Crystallographic data: orthorhombic, space group Fdd2, unit cell parameters a = 15.297(3) angstrom, b = 53.58(1) angstrom, c = 14.422(3) angstrom, V = 11821(4) angstrom(3), Z = 8.
