{5-Meth­oxy-2-[(2-morpholinoethyl)­iminometh­yl]phenolato}(thio­cyanato-κN)­nickel(II)

Abstract

In the mononuclear title complex, [Ni(C14H19N2O3)(NCS)], the nickel(II) atom is four-coordinated in a square-planar geometry by the O and N atoms of the tridentate Schiff base ligand and by the N atom of a thio­cyanate ligand. The crystal structure is stabilized by inter­molecular C—H(...)S and C—H(...)O hydrogen bonds, forming a three-dimensional network.

Comment

Nickel(II) complexes with Schiff bases have been extensively studied (Campbell & Urbach, 1973; Wallis & Cummings, 1974; Polt et al., 2003; Mukhopadhyay et al., 2003). Recently, the author reported a nickel(II) complex with the Schiff base 2-[2-(ethylamino)ethyliminomethyl]-5-methoxyphenol (Liu, 2010). In this paper, the crystal structure of the title new nickel(II) complex, with the Schiff base 5-methoxy-2-[(2-morpholin-4-ylethylimino)methyl]phenol, is reported.

The Ni atom in the title complex is four-coordinate by the phenolate O atom, imine N atom, and amine N atom of the Schiff base ligand, and by the N atom of a thiocyanate ligand, forming a square-planar geometry (Fig. 1). The bond lengths and angles involving the metal atom are comparable with those observed in similar complexes (Montazerozohori et al., 2009; Zhu et al., 2004; Zhu et al., 2006). In the crystal structure, the complex molecules are linked into a three-dimensional network by intermolecular C—H···S and C—H···O hydrogen bonds (Table 1).

Experimental

Equimolar quantities (0.1 mmol) of 4-methoxysalicylaldehyde, N-(2-aminoethyl)morpholine, ammonium thiocyanate, and Ni(CH3COO)2.4H2O were mixed and stirred in a methanol solution for 30 min at reflux. After keeping the filtrate in air for a few days, red block crystals suitable for X-ray analysis were formed.

Refinement

H atoms were placed in calculated positions and constrained to ride on their parent atoms, with C—H distances in the range 0.93–0.97 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms.

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 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.
