The Ni(II) complex comprises three Ni(II) atoms, two deprotonated L<sup>2-</sup> units, two acetate aions, two coordinated and one non-coordinated ethanol molecules. In the crystal structure, the terminal Ni(II) (Ni2 or Ni2<sup>#1</sup>) atom is located in the <em>cis</em>-N<sub>2</sub>O<sub>2</sub> coordination cavity of the L<sup>2-</sup> units and coordinated to an oxygen (O7) atom from the μ-acetato anion and an oxygen (O8) atom from the coordinated ethanol molecule in the axial positions. Meanwhile, the central Ni(II) (Ni1) atom is completed by quadruple μ-phenoxo oxygen (O3, O4, O3<sup>#1</sup> and O4<sup>#1</sup>) atoms from two L<sup>2-</sup> units and double μ-acetato oxygen (O6 and O6<sup>#1</sup>) atoms. All the Ni(II) atoms are hexa-coordinated, showing slightly distorted octahedral coordination arrangements. The Ni(II) complex is linked to form an infinite 2D layer supramolecular structure through intermolecular O-H···O, C-H···O and C-H···<span style="font-family: Symbol;">p</span> hydrogen bond interactions.</p>}, number={17}, journal={Asian Journal of Chemistry}, author={Dong, W.-K. and Meng, J.-L. and Zhang, X.-Y. and Zhao, M.-M. and Li, G. and Dong, X.-Y.}, year={2013}, month={Nov.}, pages={9970–9974} }
