Abstract
|
Ultrasound was used to synthesize nano-structures of [Ni(bpzB)2]2(1), a new two-nuclear discretecoordination compound of divalent nickel with bis-pyrazolyl borate(bpzB). The nanostructure was
characterized by scanning electron microscopy, X-ray powder diffraction, infrared, and elemental
analysis. The single-crystal X-ray data show that the coordination number of Ni(II) ions is four (Ni1N4
and Ni2N4) with square planar geometry. The supramolecular features in these complexes are guided
and controlled by weak directional intermolecular interactions. The discrete molecules interact with each
other through labile interactions, creating a 3D supramolecular framework
