Abstract top

The Schiff base ligand derived from the condensation of 3,5-dibromosalicylaldehyde and 1,2-phenylenediamine, in the presence of dimethylformamide, forms the centrosymmetric title neutral binuclear distorted complex, [Cd2(C20H10Br4N2O2)2(C3H7NO)2], with the two octahedral Cd atoms linked by two O atoms. All bond lengths and angles show normal values.

Comment top

The crystal structure and some properties of 4,4',6,6'-tetrabromo- 2,2'-[1,2-phenylenebis(nitrilomethylidyne)]diphenolato Ni(II) and Zn(II) complex were previously reported by Wang et al. (2003) and Wu et al. (2005), respectively. We report here the synthesis and crystal structure of a novel binuclear complex {bis[N,N'-1,2-phenylenediaminebis(3,5-dibromosalicylideneiminato)]- bisdimethylformamide-diCadmium(II)}. In the title compound,every molecule forms a centro-symmetric dimer and each Cd atom is six-coordinated by one oxygen atom of dimethylformamide, two O and two amino N atom of the ligand 4,4',6,6'-tetrabromo-2,2'-[1,2-phenylenebis-(nitrilomethylidyne)]diphenol and the µ-O atom from another ligand,forming a distorted octahedron (Fig. 1).

Experimental top

The title complex was synthesized in two stages. In the first stage, 3,5-dibromosalicylaldehyde was prepared according to Elzbieta et al. (1964). (1964). To ethanol (100 ml) containing 1,2-phenylenediamine (6 g), two mole equivalents of 3,5-dibromosalicylaldehyde in ethanol (50 ml) were slowly added with continuous stirring; the Schiff base molecule, viz. 4,4',6,6'-tetrabromo-2,2'-[1,2-phenylenebis(nitrilomethylidyne)]diphenol, precipitated immediately. In the second stage, the ligand (0.3 mmol), Cd(OAc)2 (0.6 mmol), DMF (30 ml) were refluxed for 2 h. The hot solution was filtered and allowed to stand at room temperature undisturbed for about one month, resulting in yellow crystals.

Refinement top

After their location in the difference map, all H-atoms were fixed geometrically at ideal positions and allowed to ride on the parent C or N atoms with Caromatic—H = 0.93 Å, Cmethine—H = 0.96 Å and N—H = 0.83 (3) Å and Uiso(H) = 1.2Ueq (C of aromatic and N) or Uiso(H) = 1.5Ueq(C of methine). Because the crystal approximated a sphere and the maximum transmission factor was 0.3943 an absorption correction was not considered necessary.

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.
