(Received 12 July 2010; accepted 10 August 2010; online 18 August 2010)

In the title complex, [Co(C10H10Br2NO)2], the CoII atom lies on a twofold rotation axis, the N2O2 units having distorted tetra­hedral coordination environments comprising two bidentate chelate 2,4-dibromo-6-(n-propyl­imino­meth­yl)phenolate Schiff base ligands [Co—N = 1.989 (3) Å, Co—O = 1.924 (2) Å and O/N—Co—O/N = 94.53 (10)–125.40 (15)°]. In the crystal structure, the mol­ecules are linked via weak inter­molecular C—H⋯O hydrogen bonds [3.334 (5) Å] and there are also short inversion-related intermolecular Br⋯Br contacts [3.4263 (6) Å]

Comment top

The Lewis base adducts of the 3,5-dibromosalicylidene compounds derived from the condensation of 3,5-dibromosalicylaldehyde with various primary amines are of interest, forming complexes with a large number of transition metals (Chen et al., 2007; Qiu et al., 2007; Maneiro et al., 2001; Bermejo et al., 1996). Recently, mononuclear zinc(II) and nickel(II) compounds of Schiff base ligands derived from the condensation of 3,5-dibromosalicylaldehyde with cyclopropylamine have been structurally characterized (Li & Wang, 2007; Yuan et al., 2007). As an extension of this work, the crystal structure of the title CoII complex, [C20H20Br4CoN2O2] (I), is reported here.

In (I), the CoII atoms have distorted tetrahedral coordination environments with two bidentate Schiff base ligands, derived from the condensation of 3,5-dibromosalicylaldehyde and n-propylamine, acting as chelates through their phenolate O and azomethine N atoms [Co—N 1.989 (3) Å; Co—O 1.924 (2) Å; bond-angle range 94.53 (10)–125.40 (15)°] (Fig. 1). The Co atoms lie on two-fold rotation axes. The C7═N1 bond length of 1.274 (4) Å is somewhat shorter than 1.284 (2) Å observed in the previously reported compound of a Schiff base ligand derived from the condensation of salicylaldehyde with n-propylamine (Li et al., 2008). The angle between the two O1—Co1—N1 planes of the molecule is equal to 84.13°. All bond lengths are within normal ranges (Allen et al., 1987). In the crystal structure, the molecules are linked via weak intermolecular C—H···O hydrogen bonds and there are also short inversion-related inermolecular Br···Br contacts [3.4263 (6) Å] (Fig. 2).

Experimental top

3,5-Dibromosalicylaldehyde (560 mg, 2 mmol) and n-propylamine (118 mg, 2 mmol) were dissolved in methanol (25 ml). The mixture was stirred for 30 min to give an orange solution, which was added to a methanol solution (15 ml) of Co(NO3)2.6H2O (280 mg, 1 mmol). The mixture was stirred for another 20 min at room temperature to give a red solution and then filtered. The filtrate was kept in air for 5 d, forming red blocky crystals. The crystals were isolated, washed three times with distilled water and dried in a vacuum desiccator containing anhydrous CaCl2 (yield 68%). Analysis calculated for C20H20Br4CoN2O2: C 34.37, H 2.88, N 4.01%; found: C 34.17, H 2.90, N 3.99%.

All the H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.97 Å, and with Uiso(H) = 1.2Ueq(carrier) or 1.5Ueq(methyl groups).

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.
