In the title compound, [Co(C8H6N3)2(C2H8N2)]NO3·H2O, the CoIII ion is coordinated by four N atoms from two 2-(pyridin-2-yl)-1,3-imidazol-1-ide ligands and two N atoms of ethyl­enediamine in a distorted octa­hedral geometry. In the crystal, classical N—H⋯N(O) and O—H⋯N(O) hydrogen bonds connect all the isolated components together to yield a three-dimensional structure.

Comment top

Organometallic complexes with the 2-(2-pyridyl)imidazole ligand (Dosser & Underhill, 1972; Lan et al., 2008) are intensively studied due to their magnetic properties (Carranza et al., 2009; Schott et al., 2011). Herewith we report the crystal structure of the title compound, (I) - a Co(III) complex with 2-(2-pyridyl)imidazolato ligands.

In (I) (Fig. 1), Co(III) ion is chelated by one ethylenediamine and two 2-(2-pyridyl)imidazolato ligands being coordinated by six N atoms in a distorted octahedral geometry. The bite angles of ethylenediamine and 2-(2-pyridyl)imidazolato chelate ligands to the cobalt atom are ca 84.72 (11)° and 89.02 (11)°, respectively. An extensive hydrogen-bonding network (Table 1) involving the N atoms of the ethylenediamine and 2-(2-pyridyl)imidazolato ligands, the water molecule and O atoms of nitrate anion interconnect all the isolated moieties together to yield a three-dimensional structure (Fig. 2).

Experimental top

An ethanol solution (7 ml) of 2-(2-pyridyl)imidazole (0.5 mmol) was slowly added to an aqueous solution (8 ml) of Co(NO3)2.6H2O (0.5 mmol) and ethylenediamine (2 mmol). Red block crystals were obtained after two months.

Refinement top

All H atoms were geometrically positioned (C—H = 0.93–0.97 Å; O—H = 0.85 Å; N—H = 0.90 Å) and treated as riding, with Uiso(H) = 1.2Ueq of the parent atom.

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.
