Abstract top

The molecule of the title compound, [NaNi(C18H18N2O4)(C2N3)(H2O)], is approximately planar, with a maximum deviation from the molecular plane of 0.770 (5) Å. The coordination environment of the Ni2+ ion is distorted square-planar and it is N2O2 coordinated by the 6,6'-dimethoxy-2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolate Schiff base ligand. The Na+ atom is chelated by the four O atoms of the Schiff base ligand, a water ligand and a dicyanamide anion. The structure displays intermolecular O-H...N hydrogen bonding.

Comment top

The dicyanamide ligand N(CN)2, has attracted continuous attention in the past four years for the buildup of interesting extended architectures. Its versatile coordination behavior and its ability to organize solids into polymeric structures with a rich diversity of magnetic properties have attracted interest toward this research area (Ohba et al., 2000). N,N-disalicylideneethylenediamine type Schiff bases ligands present versatile steric, electronic and lipophilic properties (Correia et al. 2005). We report here the synthesis and crystal structure of the title compound. The molecular structure is shown in Fig. 1. The values of the geometric parameters in this compound are normal (Costes et al., 2004). NiII and NaI are connected via two bridging O atoms of the ligand. The six-coordinate Na atom adopts a distorted octahedral coordination geometry while the four-coordinate Ni gives a planar coordination geometry.

Experimental top

A mixture of 6,6'-dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene)diphenol (1 mmol) and nickel chloride (1 mmol) in methanol (15 ml) was stirred for 30 min and sodium dicyanamide (1 mmol) was added, stirred for another 15 min and then filtered. The resulting clear orange solution was vapor at room temperature for 7 d, after which large orange block-shaped crystals of the title complex suitable for X-ray diffraction analysis were obtained.

Refinement top

The H atoms were fixed geometrically and were treated as riding on their parent C atoms, with C—H distances in the range of 0.93–0.97 Å and with Uiso(H) = 1.2Ueq(parent atom), or Uiso(H) = 1.5Ueq(Cmethyl).

Special details top

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.
