In the title complex, [Ni(C21H15ClN2O2)], the NiII ion is coordinated by two N and two O atoms from the tetradentate Schiff base ligand in a distorted square geometry. The crystal packing exhibits short intermolecular Ni⋯Ni distances of 3.273 (3) Å.

The synthesis of the title complex was carried out by reaction of Ni(ClO4)2.6H2O and the Schiff-base ligand with the molar ratio 1:1 in methanol under the stirring condition at room temperature. The filtrated solution was left to slowly evaperate in air to obtain single-crystal suitable for X-ray diffraction with the yield about 56%.
C-bound H atoms were placed in idealized positions with C—H distances of 0.93 and 0.96 Å, and were refined as riding atoms, with Uiso(H) = 1.2-1.5 Ueq(C).
Schiff-base ligands, due to their excellent coordination ability, have been widely introduced into the coordination chemistry. Here, we report a new nickel complex based on a tetradentate Schiff-base ligand.
In the title compound (Fig. 1), the whole molecule is essentially planar with the mean deviation 0.0523 Å from the plane formed by all non-hydrogen atoms. The NiII ion is four-coordinated by two N atoms and two O atoms of the Schiff base ligand. The Ni—O and Ni—N bond lengths are all consistent with those found in other reported tetradentate Schiff base Ni complexes (Ali, et al., 2010; Hernandez-Molina, et al., 1997; Niu, et al., 2009; Radha, et al., 1985).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Schiff-base ligands, due to their excellent coordination ability, have been widely introduced into the coordination chemistry. Here, we report a new nickel complex based on a tetradentate Schiff-base ligand.
In the title compound (Fig. 1), the whole molecule is essentially planar with the mean deviation 0.0523 Å from the plane formed by all non-hydrogen atoms. The NiII ion is four-coordinated by two N atoms and two O atoms of the Schiff base ligand. The Ni—O and Ni—N bond lengths are all consistent with those found in other reported tetradentate Schiff base Ni complexes (Ali, et al., 2010; Hernandez-Molina, et al., 1997; Niu, et al., 2009; Radha, et al., 1985).
