[Ni(1,2-PDA)3]2(HOCH2CH2CH2NH3)3(H3O)2 [Ge7O14X3]3 (X = F, OH): A New 1D Germanate with 12-Ring Hexagonal Tubular Channels

A novel one-dimensional germanate [Ni(1,2-PDA)3]2(HOCH2CH2CH2NH3)3 (H3O)2[Ge7O14X3]3 (X = F, OH) made of Ge7 clusters has been prepared with 12-ring hexagonal tubular channels. The metal complex [Ni(1,2-PDA)3]2+ is self-assembled during the solvothermal synthesis and acts as the structure-directing agent (SDA) along with 3-amino-1-propanol, which plays a dual role of SDA and solvent.
