In the title compound, [Co(C3H2O4)(C14H12N2)]n, the CoII ion is in a distorted octa­hedral coordination being chelated by a 2,9-dimethyl-1,10-phenanthroline mol­ecule (dmphen) and two carboxyl­ate groups of two malonate ligands The malonate ligand acts in a bridging mode, forming coordination chains along [100]. ππ stacking inter­actions between dmphen ligands [inter­planar distances = 3.414 (4) and 3.447 (4) Å] organize the coordination polymers into supra­molecular double chains.

Comment top

Metal-phenanthroline complexes and their derivatives have attracted much attention because of their peculiar features. In turn dicarboxylate ligands play an important role in modern coordination chemistry and many complexes have been published with them as ligands (Rao et al., 2004; Zheng et al., 2004). The title complex, (I), was recently prepared and its crystal structure is reported here.

The crystal structure of the title compound consists of [Co(C14H12N2)(C3H2O4)]n chains (Fig. 1). Each Co atom is surrounded by two nitrogen atoms of one 2,9-dimethyl-1,10-phenanthroline ligand and four oxygen atoms of two bis-chelating malonate anions to complete a seriously distorted octahedral coordination (Table 1). The malonate ligands bridge the Co atoms to form neutral one-dimensional chains [Co(C14H12N2)(C3H2O4)]n along [100] with parallel orientated phen ligands at the same side. As shown in Fig. 2, through π-π stacking interactions the dmphen ligands of two adjacent coordination chains form supramolecular double chains. The interplanar distances between the neighbouring dmphen ligands are 3.414 (4) and 3.447 (4) Å.

Experimental top

Addition of 2.0 ml (1 M) NaOH to an aqueous solution of CoCl2.6H2O (0.238 g, 1.00 mmol) in 10.0 ml H2O produced a pink precipitate, which was centrifugated and washed with doubly destilled water for several times until no Cl- anions were detectable. The fresh precipitate was then added to a stirred solution of malonic acid (0.104 g, 1.00 mmol) and 2,9-dimethyl-1,10-phenanthroline hydrate (0.226 g, 1 mmol) in CH3OH/H2O (1:1 30 ml). The red mixture was allowed to stand at room temperature and after several days, red plate-like crystals suitable for X-ray analysis were formed. grown by slow evaporation.

Refinement top

All H atoms were placed in geometrically calculated position (C-H = 0.93-0.97 Å) and refined in a riding model approximation with Uiso(H) = 1.2 Ueq(C).

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.
