| Abstract: | A borate compound Ni(en)3]B5O6(OH)4]CH3COO] (1) has been synthesized under mild hydrothermal conditions. The newly synthesized compound was characterized by single-crystal X-ray diffraction, elemental analysis and thermogravimetry. The three-dimensional (3D) supramolecular open-framework of compound 1 is constructed by inorganic B5O6(OH)4]? building units and organic CH3COO]? anions through hydrogen bonds, and the charge-balancing Ni(en)3]2 + cations are located in 3D channels. It is very interesting that there exist two helical chains formed by B5O6(OH)4]? building units and organic CH3COO]? anions through hydrogen bonds in compound 1 along different axes. Magnetic measurement indicates that compound 1 exhibits paramagnetic behavior down to 4 K. |
