The molecule of the title compound, [CuNa(C₁₈H₁₈N₂O₄)(C₂N₃)(H₂O)], is almost planar, the maximum deviation from the molecular plane being 0.48 (4) Å. The coordination environment of the Cu²⁺ ion is distorted square-planar and it is N₂O₂-chelated by the Schiff base ligand. The Na⁺ cation has a distorted octahedral environment defined by the four O atoms of the 6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolate ligand, a water ligand and a dicyanamide anion.

Comment top

The dicyanamide ligand N(CN)₂, has attracted 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 (I) are normal (Costes et al. 2004) (Table 1). The copper and sodium cations are connected via two bridging oxygen atoms of the ligand. The Na atom is coordinated by the four O atoms of the 6,6'-Dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene)diphenol ligand, a water ligand and a dicyanamide anion while the four-coordinate Cu gives a planar coordination.

Experimental top

A mixture of 6,6'-Dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene)diphenol (1 mmol) and copper 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 blue solution was vapor at room temperature for 7 days, after which large blue block-shaped crystals of the title complex suitable for X-ray diffraction analysis were obtained.

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.
