The metal atom of the title compound is four coordinated. The asymmetrically appended Cl atom and a widely spread π-conjugated system of the complex molecule construct the supramolecular structures of a hydrogen-bonded chain and a π–π interacted column.

Keywords: crystal structure, nickel(II) complex, 2-aminobenzaldehyde, asymmetric structure, supramolecular structure

Abstract

The title complex, [Ni(C₂₀H₁₄ClN₃O)], with an asymmetrically chloride-appended Schiff base ligand has been synthesized and structurally characterized at 100 K. In the compound, the central nickel(II) ion has a square-planar coordination geometry with N₃O donors of the π-conjugated tetradentate Schiff base ligand. In the crystal, the complexes are connected into an inversion dimer via an Ni⋯Ni interaction [3.1753 (5) Å] and a pair of π–π interactions [centroid–centroid distance = 3.8416 (16) Å]. The dimers are linked via a C—H⋯Cl hydrogen bond, forming a chain along the c-axis direction. The dimer chains interact with each other through π–π interactions [centroid–centroid distance = 3.8736 (16) Å], forming a layer expanding parallel to the ac plane.

Chemical context

Metal complexes with a tetradentate Schiff base ligand as represented by H₂(salen) [N,N′-ethylenebis(salicylideneimine)] and its derivatives have played extremely important roles in the field of coordination chemistry. Up to now, a large number of salen derivatives have been prepared and used for complexation in the expectation of a wide range of features such as catalytic ability, magnetic, dielectric and luminescence properties and so on (Bermejo et al., 1996 ▸). In these cases, symmetric tetradentate ligands mainly produce N₂O₂ or N₄ type coordination environments. In this research, we have designed asymmetric structures, both in the coordination environment and in the molecular configuration, for the construction of the supramolecular structure through intermolecular hydrogen bonds, and synthesized the title nickel(II) complex using an asymmetrically chloride-appended tetradentate Schiff base ligand.

The structure of the title compound, which features a widely spread π-conjugated ring system, is also useful for supramolecular assemblies through π–π interactions. The mononuclear copper(II) complex with a similar N₃O type asymmetrical ligand was reported by Ghorai & Mukherjee (2014 ▸).

Structural commentary

The nickel(II) atom is in a square-planar coordination with an asymmetrical coordination environment formed by the N₃O donor set including one phenolate O atom, two imine N atoms and one amino N atom of the tetradentate Schiff base ligand (Fig. 1 ▸). The Ni—O1, Ni—N1, Ni—N2, and Ni—N3 bond lengths are 1.8617 (18), 1.878 (2), 1.896 (2) and 1.831 (2) Å, respectively. The complex molecule is approximately planar; the coordination plane (N1–N3/O1/Ni1) makes dihedral angles of 4.15 (12), 10.22 (12) and 13.42 (12)°, respectively, with the C1–C6, C8–C13 and C15–C20 benzene rings.

Supramolecular features

In the crystal, pairs of complex molecules related by an inversion centre are dimerized by an Ni⋯Ni interaction [3.1753 (5) Å] and a pair of π–π interactions between the C1–C6 and C15–C20 benzene rings [centroid–centroid distance = 3.8415 (16) Å]. Such dimerization caused by an Ni⋯Ni interaction has also been observed in symmetric Ni(salen) compounds (Aullón et al., 1996 ▸; Siegler & Lutz, 2009 ▸). The dimeric molecules of the title compound are linked by C—H⋯Cl hydrogen bonds (Table 1 ▸), producing a chain of dimers along the c axis (Fig. 2 ▸). The dimers further interact with each other through π–π interactions between the C1–C6 and C8–C13 benzene rings [centroid–centroid distance = 3.8738 (17) Å], forming a column along the a axis (Fig. 3 ▸). Together, these C—H⋯Cl and π–π interactions result in a layer parallel to the ac plane. The layers are further linked by a short C—H⋯C contact (Table 1 ▸), giving a three-dimensional network (Fig. 4 ▸).

Synthesis and crystallization

The tetradentate Schiff base ligand was prepared by the reaction of 2-aminobenzaldehyde (Smith & Opie, 1948 ▸) (0.228 g, 2.0 mmol) and 2-amino-4-chlorophenol (0.144 g, 1.0 mmol) in methanol (50 ml) under stirring for 1 h. The resulting solution including the ligand was used for complexation with the Ni^II ion. A methanol solution (50 ml) of Ni(CH₃COO)₂·4H₂O (0.249 g, 1.0 mmol) was added to the solution and stirred for 1 h. The resulting solution was allowed to stand for a few days, during which time dark-purple block-shaped crystals precipitated. They were collected by suction filtration and dried in air to give single crystals of the title compound suitable for X-ray diffraction.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The position of the N-bound H atom was refined with N—H = 0.86 (1) Å and U _iso(H) = 1.5U _eq(N). Other H atoms were treated as riding with C—H = 0.95 Å and U _iso(H) = 1.2U _eq(C).

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F². R-factor (gt) are based on F. The threshold expression of F² > 2.0 sigma(F²) is used only for calculating R-factor (gt).
