摘要：

An organically-templated chiral borogermanate (CH3NH3)(2)[Ge(B4O9)] (1), has been solvothermally synthesized and characterized by elemental analysis, IR, PXRD, TGA, single-crystal X-ray diffraction and UV-vis spectrum. It crystallized in the monoclinic space group C2 (No. 5) with a=10.249(1) angstrom, b=9.449(1) angstrom, c=6.956(2)angstrom, beta=131.76(2)degrees, V=502.43(19)angstrom(3), Z=2. The structure is constructed by alternate linkage of GeO4 tetrahedra and B4O9 clusters to form a zeotype framework with diamond topology. Four intersecting channels with different sizes are observed. Large circular 10-ring channels are clearly extended along the [001] direction, 9-ring channels are running along the [101], [110], and [112] directions, respectively. Additionally, two pairs of the right- and left-handed channels couple together along the [100] and [010] directions, respectively. The preliminary investigations show that compound 1 exhibits second-harmonic generation (SHG) response and ferroelectric properties. (C) 2010 Elsevier B.V. All rights reserved.
