In the title compound, [Co(C12H8N2)2(C2H4N2O4)](NO3)2·2H2O, the Co atom has a distorted octa­hedral coordination formed by six N atoms from one dihydroxy­glyoxime and two 1,10-phenanthroline ligands. The mol­ecules are linked into a three-dimensional framework by O—H...O, C—H...O, C—H...N and O—H...N hydrogen bonds and by π–π stacking inter­actions [centroid–centroid distance = 3.585 (3) Å; sym­metry code: 1-x, 2-y, -z].

Comment top

The crystal structure of bis(1,10-phenanthroline-N,N')(dihydroxy glyoxime) copper(II) dinitrate dihydrate, (II), has previously been reported (Liu et al., 2007). The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with that of (II).

In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The six nitrogen atoms are coordinated to the cobalt atom, in a distorted octahedral arrangement (Table 1). The dihydroxyglyoxime and two phen ligands are each planar and the phen ligands are nearly perpendicular to each other, with a dihedral angle of 86.94 (7)°, as in (II).

In the crystal structure, the molecules are linked into a three-dimensional framework (Fig. 2) by O—H···O, C—H···O, C—H···N and O—H···N hydrogen bonds (Table 2). There are stacking interactions between adjacent phen ligands with centroid-centroid distance of 3.585 (3)Å (symmetry code: 1 - x, 2 - y, -z) leading to a supramolecular network structure (Fig. 2), as in (II).

Experimental top

Cobalt dinitrate hexahydrate (146 mg, 0.5 mmol), phen (198 mg, 1 mmol) and dihydroxyglyoxime (120 mg, 1 mmol) were dissolved in ethanol (15 ml). The mixture was heated for 5 h under reflux with stirring. It was then filtered to give a clear solution, into which diethyl ether vapour was allowed to condense in a closed vessel. After being allowed to stand for a few days at room temperature, some pink single crystals suitable for X-ray diffraction analysis precipitated.

Refinement top

H atoms of the water molecules were located in a difference synthesis and refined isotropically [O—H = 0.833 (10)–0.86 (8) Å, Uiso(H) = 0.532 (13)–0.603 (11) Å2]. The remaining H atoms were positioned geometrically, with O—H = 0.82 Å (for OH) and C—H = 0.93 Å for aromatic H, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,O), where x = 1.2 for aromatic H atoms and x = 1.5 for all other H atoms.

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.
