| description | Among their many applications, metal pincer complexes are of interest for their properties as catalysts in cross-coupling reactions. Pincer ligands exhibit tridentate coordination to the metal center and occupy the meridional positions forming two chelate rings. The two Ni(II) POCOP pincer complexes with a fluorothiophenolate ligand reported herein, with formulas [Ni(SC<sub>6</sub>F<sub>4</sub>-4-H){C<sub>6</sub>H<sub>2</sub>-3-(C<sub>2</sub>H<sub>3</sub>O)-2,6-(OP<i><sup>i</sup></i>Pr<sub>2</sub>)<sub>2</sub>}] (<b>2</b>) and [Ni(SC<sub>6</sub>F<sub>5</sub>){C<sub>6</sub>H<sub>2</sub>-3-(C<sub>2</sub>H<sub>3</sub>O)-2,6-(OP<i><sup>i</sup></i>Pr<sub>2</sub>)<sub>2</sub>}] (<b>3</b>), are isostructural. Additionally, they are prepared in a facile manner from the chloride compound [NiCl{C<sub>6</sub>H<sub>2</sub>-3-(C<sub>2</sub>H<sub>3</sub>O)-2-6-(OP<i><sup>i</sup></i>Pr<sub>2</sub>)<sub>2</sub>}] (<b>1</b>). The complexes exhibited slightly distorted square planar geometries around the metal. The fluorothiophenolate ligands are responsible of the C—H···F, C—F···π and C=O···π<sub>F</sub> interactions that contribute to stabilize the crystal structure arrays. |
