Abstract top

In the title compound, {[Co(C10H14N4)2(H2O)2](NO3)2}n, the CoII ion lies on an inversion center and is six-coordinated in an octahedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms from the two water molecules. The CoII atoms are bridged by ligands, generating a two-dimensional (4,4)-network. Adjacent fishnet planes are linked to the nitrate anions via O-H...O hydrogen bonds, forming a three-dimensional supramolecular structure.

Comment top

The 1,1'-butane-1,4-diyldiimidazole as a flexible ligand exhibit a variety of supramolecular aggregation patterns (Ma et al., 2003; Dong et al., 2006; Yu et al., 2008). In this paper, we report the new title compound, (I), synthssized by the reaction of 1,1'-butane-1,4-diyldiimidazole ligand and cobalt dinitrate in aqua solution.

In (I), each CoII atom is located on a inversion centre and is six-coordinated in an octahedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms form the two water molecules (Fig. 1). The Co—N and Co—O distances are normal (Table 1). The CoII atoms are bridged by ligands, generating a two-dimensional (4,4)-network (Fig. 2).

In the crystal, a R44(12) motif is built up by O—H···O hydrogen bonding interaction between the uncoordinated nitrate anions and the coordinated water molecules,which linke the adjacent fishnet planes to a three-dimensional supramolecular structure (Fig. 3, Table 2).

Experimental top

1,1'-Butane-1,4-diyldiimidazole ligand was prepared from imidazole and 1,4-dibromobutane in DMSO (Ma et al., 2003a). 1,1'-Butane-1,4-diyldiimidazole (0.76 g, 4 mmol) and cobalt dinitrate (0.73 g, 4 mmol) were dissolved in hot aqua solution (10 ml) to give a clear solution. The resulting solution was allowed to stand in a desiccator at room temperature for a week, pink crystals of (I) were obtained.

Refinement top

H atoms bound to C atoms were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93 Å (aromatic), C—H = 0.97 Å (methylene), and with Uiso(H) = 1.2Ueq(C). Water H atoms were initially located in a difference Fourier map, but they were treated as riding on their parent atoms with O—H = 0.85 Å and with with Uiso(H) = 1.5Ueq(O).

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.
