In the title compound, [Ni(NCS)2(C13H19N3O)(H2O)], the NiII ion is six-coordinated by the N,N′,N′′-tridentate Schiff base, the N atoms of two thiocyanate ligands and one water O atom in a distorted octahedral geometry. Intramolecular C—H⋯N and C—H⋯O hydrogen bonds occur. In the crystal, O—H⋯S, O—H⋯O and C—H⋯S hydrogen bonds link adjacent molecules into layers parallel to the ac plane.

A mixture of 2-acetylpyridine (0.20 g, 1.65 mmol) and 4-(2-aminoethyl)morpholine (0.21 g, 1.65 mmol) in ethanol (20 ml) was refluxed for 2 hr followed by addition of a solution of nickel(II) acetate tetrahydrate (0.41 g, 1.65 mmol) and sodium thiocyanate (0.134 g, 1.65 mmol) in a minimum amount of water. The resulting solution was refluxed for 30 min, then left at room temperature. The crystals of the title complex were obtained in a week.
The C-bound H atoms were placed at calculated positions (C—H 0.95–0.99 Å) and were treated as riding on their parent C atoms. The O-bound H atoms were located in a difference Fourier map, and refined with a distance restraint of O—H 0.84 (2). For all H atoms, Uiso(H) values were set to 1.2–1.5 Ueq(carrier atom). An additional rigid-bond type restraint (DELU in SHELXL97) was placed on the displacement parameters of S1 and C14; S2 and C15.
The title mixed-ligand nickel(II) complex was obtained by following a similar synthetic procedure as for its analogous copper(II) complex (Suleiman Gwaram et al., 2011). However, compared to the square-pyramidal environment around the CuII ion, afforded by the tridentate Schiff base and the N atoms of two SCN-, the NiII ion is coordinated by one additional water ligand to have an octahedral geometry. The Ni—N and Ni—O bond lengths in this complex are comparable to those in the similar structures (Chiumia et al., 1999; Zhao et al., 2008). In the crystal, the adjacent molecules are linked together through O—H···S, O—H···O and C—H···S hydrogen bonds into layers parallel to the ac plane. An S···S interaction [3.5276 (7) Å] between S1 and S2 of the symmetry related molecule at -x, y + 1/2, -z + 3/2, connects the layers into a three-dimensional network. Intramolecular C—H···N and C—H···O hydrogen bonding are also observed.

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. |

The title mixed-ligand nickel(II) complex was obtained by following a similar synthetic procedure as for its analogous copper(II) complex (Suleiman Gwaram et al., 2011). However, compared to the square-pyramidal environment around the CuII ion, afforded by the tridentate Schiff base and the N atoms of two SCN-, the NiII ion is coordinated by one additional water ligand to have an octahedral geometry. The Ni—N and Ni—O bond lengths in this complex are comparable to those in the similar structures (Chiumia et al., 1999; Zhao et al., 2008). In the crystal, the adjacent molecules are linked together through O—H···S, O—H···O and C—H···S hydrogen bonds into layers parallel to the ac plane. An S···S interaction [3.5276 (7) Å] between S1 and S2 of the symmetry related molecule at -x, y + 1/2, -z + 3/2, connects the layers into a three-dimensional network. Intramolecular C—H···N and C—H···O hydrogen bonding are also observed.
