Synthesis of the N-(8-quinolylmethyl)iminodiethanol ligand. 8-bromomethylquinoline (0.01 mol) was added to the solution of diethanolamine (0.03 mol) in ethanol (50 ml) with stirring. The mixture was refluxed for 15 h, and the solvent was evaporated. The residual oil was dissolved in 10 ml H2O, and the mixture was extracted with benzene and dried over MgSO4. The solvent was evaporated to give a pale yellow liquid, 1.92 g (78% yield). IR (cm-1): 3357vs, 2926 s, 2869 s, 1454 s, 1425m, 1321m, 1130m, 1071 s, 1438 s, 834m. 1H NMR (CDCl3): 4.21 (2H,S,-CH2Ar), 8.88 (1H, d, Ar—H2), 7.41 (1H, t, Ar—H3), 8.16 (1H, d, Ar—H4), 7.75 (1H, d, Ar—H5), 7.47(1H, t, Ar—H6), 7.57 (1H, d, Ar—H7), 2.74 (4H, t, NCH2C), 3.62 (4H, t, CH2O), 1.25 (2H, s, OH). Anal. Found: C, 68.51; H, 7.62; N, 11.39%; calculated for C14H18N2O2: C, 68.27; H, 7.37; N, 11.37.
Synthesis of the title complex (I). Solid KSCN (0.2 mmol) was added slowly with continuous stirring to a solution of NiSO4.6H2O (0.1 mmol) in distilled water (15 ml), the ligand (0.1 mmol) was dissolved in methanol (15 ml) and two solutions were mixed. The mixture was filtered, and green crystals suitable for X-ray
were obtained by slow evaporation from the resulting solution at room temperature. Anal. Found: C, 43.28; H, 4.63; N, 12.78%; calculated for C16H20N4NiO3S2: C, 43.76; H, 4.59; N, 12.76%.H atoms were included in calculated positions refined as part of a riding with C—H distances of 0.93 Å (aromatic H) and 0.97 Å (ethyl H), and with Uiso(aromatic H, ethyl H) = 1.2Ueq(C). H atoms bonded to O atoms were located in a difference map and refined with distance restraints of O—H = 0.93 Å (hydroxy H) and 0.852Å (H2O molecular H), and with Uiso (hydroxy H)= 1.2Ueq(O) and Uiso (H2O molecular H) = 1.5Ueq(O).
As shown in Fig. 1, (I) is a neutral mononuclear complex, consisting of one nickel(II) ion, one N-(8-quinolylmethyl)iminodiethanol ligand, two SCN- and one uncoordinated H2O molecule. Each NiII center has a distorted octahedral geometry (Table 1) comprised of two isothiocyanate N atoms, the quinoline N donor, the tertiary N donor and two O donor of the ligand. The NSC groups are almost linear [178.9 (3)° and 178.2 (4)°], though he Ni—N—C linkage [158.8 (3)° and 171.5 (3)°] is bent. No intermolecular hydrogen bonds interactions were observed in the complex.

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. |

As shown in Fig. 1, (I) is a neutral mononuclear complex, consisting of one nickel(II) ion, one N-(8-quinolylmethyl)iminodiethanol ligand, two SCN- and one uncoordinated H2O molecule. Each NiII center has a distorted octahedral geometry (Table 1) comprised of two isothiocyanate N atoms, the quinoline N donor, the tertiary N donor and two O donor of the ligand. The NSC groups are almost linear [178.9 (3)° and 178.2 (4)°], though he Ni—N—C linkage [158.8 (3)° and 171.5 (3)°] is bent. No intermolecular hydrogen bonds interactions were observed in the complex.
