Abstract [en]

An open-framework germanate denoted as SU-79 with the chemical formula [Ge12.5O26(OH)(2)]-[Ni(C3N2H10)(2)](1.1)(NH4)(0.8)(C3N2H12)(0.5)(C3N2H10)(1.5)(H2O)(2) has been synthesized under hydro/solvothermal conditions using [Ni(1,2-pda)(2)](2+) (1,2-pda = 1,2-diaminopropane) and 1,2-pda as templates. Owing to the complicated pseudo-merohedral twinning in the crystals, the rotation electron diffraction (RED) method was used for the unit cell and space group determination. The structure of SU-79 was solved and refined based on synchrotron single crystal X-ray diffraction data. SU-79 exhibits a 3D open germanate framework built with Ge-13 clusters, consisting of a 3D channel system with interconnected 10- and 11-ring channels. Interestingly, helical GeO4 tetrahedral chains with left-handed/right-handed chirality were found in the structure. The [Ni(1,2-pda)(2)](2+) complexes, adopting in a square-planar geometry, show a structure directing role on the SU-79 framework via hydrogen bonds. Comparing with its related structure, SU-67, the formation of the pseudo-merohedric twinning in SU-79 was also discussed.
