In the title complex, [Ni(C11H16N3O)]Cl·2H2O, the NiII ion is coordinated within a distorted square-planar environment. In the crystal, intermolecular N—H⋯Cl, N—H⋯O, O—H⋯O, O—H⋯Cl and weak C—H⋯O hydrogen bonds link the components into a two-dimensional network parallel to (001).

NiCl2.6(H2O) (1 mmol, 238 mg), salicylaldehyde (1 mmol, 122 mg) and diethylenetriamine (1 mmol, 103 mg) were dissolved in a mixture of ethanol and acetonitrile (50 ml, 1:1 v/v), resulting in a light-green solution. When diethyl ether was slowly diffused into this solution for one week, pale-yellow blocks suitable for X-ray diffraction were formed at the bottom of the vessel.
All the H atoms bonded to carbon atoms were located at their geometrical positions with C–H = 0.97 Å(methylene) and 0.93 Å(aromatic), Uiso(H) = 1.2Ueq(C). H atoms bonded to imine N and water O atoms were located on the difference Fourier maps and then refined with the constraints of N—H = 0.86 (2) Å, O—H = 0.82 (2) Å, H—H = 1.35 (2)Å and the Uiso(H) values were set 1.2 times of Ueq(N) or 1.5 times of Ueq(O) of their carrier atoms.
The Schiff base ligand 2-((2-(2-aminoethylamino)ethylimino)methyl)phenol has often been used in the synthesis of metal-organic complexes (Chen & Wang, 2006, Cusmano Priolo et al., 1983, Kratochvíl et al., 1989, Kratochvíl et al.,1991, Loub et al., 1990, Loub et al., 1989, Podlahová et al., 1988, Rotondo et al., 1983, Zhang et al., 2006, Zhu et al.,2004, Liu et al., 2004). In this paper, we report the title mononuclear metal complex (I).
In (I), the
consists of a coordination cation, one uncoordinated Cl- anion and two solvent water molecules (Fig.1). The NiII ion is in a distorted square-planar coordination environmemt with atom Ni1 atom 0.058Å from the plane formed by N1/N2/N3/O1. The Ni—N/O bond lengths are comparable to previously published analogs (Loub et al., 1989, Podlahová et al., 1988).The
is stabilized by intermolecular hydrogen bonds (Table 1), forming a two-dimensional network parallel to the (001) plane (Fig.2).For related structures, see: Chen & Wang (2006); Cusmano Priolo et al.

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 Schiff base ligand 2-((2-(2-aminoethylamino)ethylimino)methyl)phenol has often been used in the synthesis of metal-organic complexes (Chen & Wang, 2006, Cusmano Priolo et al., 1983, Kratochvíl et al., 1989, Kratochvíl et al.,1991, Loub et al., 1990, Loub et al., 1989, Podlahová et al., 1988, Rotondo et al., 1983, Zhang et al., 2006, Zhu et al.,2004, Liu et al., 2004). In this paper, we report the title mononuclear metal complex (I).
In (I), the asymmetric unit consists of a coordination cation, one uncoordinated Cl- anion and two solvent water molecules (Fig.1). The NiII ion is in a distorted square-planar coordination environmemt with atom Ni1 atom 0.058Å from the plane formed by N1/N2/N3/O1. The Ni—N/O bond lengths are comparable to previously published analogs (Loub et al., 1989, Podlahová et al., 1988).
The crystal structure is stabilized by intermolecular hydrogen bonds (Table 1), forming a two-dimensional network parallel to the (001) plane (Fig.2).
