With an aim of understanding the coordination chemistry of flexible ligands and developing new open framework materials, we synthesized an organic–inorganic hybrid borate in the BAVAO system, it is similar with [Zn(en)2]6[(VO)12O6B18O39(OH)3]13H2O.
The structure revealed an interesting elliptical housing, there are six nickel atoms coordinated with two ethylenediamine molecules.
Herein we present its hydrothermal synthesis and crystal structure, infrared spectroscopy, UV–Vis diffuse reflectance spectrum, and TG properties.
