(Received 4 February 2013; accepted 23 February 2013; online 2 March 2013)

The title compound, {[Co(C10H8N2)2(H2O)2](NO3)2·4H2O}n, (C10H8N2 = 4,4′-bipyridine = 4,4′-bpy) is a layered coordination polymer built up from a cationic square grid extending in (101) enclosing uncoordinating nitrate ions and water mol­ecules. The CoII ion has site symmetry 2 and one of the 4,4′-bpy ligands is generated by twofold symmetry [two N atoms and two C atoms lie on the rotation axis and the dihedral angle between the pyridine rings is 45.66 (5)°]. The other 4,4′-bpy ligand is generated by a crystallographic inversion center. The CoII ion exhibits a slightly distorted octa­hedral coordination geometry defined by two O atoms of two coordinating water mol­ecules and four N atoms from four bridging 4,4′-bpy ligands. The structure is consolidated by O—H⋯O, C—H⋯O and C—H⋯N hydrogen bonds.

Comment top

The structure of (I) is a two dimensional layer with no interpenetration and no enclathration of organic guest molecules. The CoII atom being located on a twofold crystallographic axis, has slightly distorted octahedral geometry, being ligated by two aqua ligands [Co—O1w = 2.074 (10) Å] and four pyridil groups from 4,4'-bpy ligands (Fig. 1), with a distance Co—N in the range of 2.1898 (13) - 2.2306 (14) Å which is almost similar to that observed in {[{Co(H2O)2}(µ-4,4'-bpy)2][NO3]2. 2(4,4'-bpy).2H2O}n; {[{Co(H2O)2(4,4'-bpy)2}(µ-4,4'-bpy)]. 1.5[NO3].0.5OH. 2(4,4'-bpy).2.5H2O}n, Felloni et al. (2002) and {[Co(µ-4,4'-bpy)(4,4'-bpy)2(H2O)2].(OH)3.(NMe4).4,4'-bpy.4H2O}n, Jin et al. (2006), these last act as a bidentate bridging ligands giving rise to a 2-D square grid sheet of (4,4) topology lying in the (101) plane. The basal coordinated 4,4'-bpy is located on an inversion center, it is planar with a 0° interplanar angle between the two pyridil rings, the same thing is observed in {[Cd(4,4'-bpy)2(H2O)2]. (NO3)2.4H2O}n, Aoyagi et al. (2000), whereas the axially one is nonplanar with an angle of 45.60° between the pyridil rings. The dihedral angle between the two basal coordinated 4,4'-bpy molecules is 46.92°. Each layer features a perfectly planar, though slightly distorted, square with Co(II) atom and 4,4'-bpy at each corner and side, respectively (cis N—Co—N = 88.64 (2)°, 91.37 (2)°) (Fig. 2). The square cavity has dimensions of 11.54 × 11.59 Å, which are comparable to those of closely related compound {[Cd(4,4'-bpy)2(H2O)2].(NO3)2.2H2O}n, Tong et al. (2000). The nitrate ion and lattice water molecules are situated between the coordination layers and form extensive hydrogen bonds among the aqua ligands, 4,4'-bpy, uncoordinated water molecules and nitrate ion, which extend the two-dimensional coordination layers into a three-dimensional molecular network (Fig. 3).

Experimental top

A mixture of Co(NO3)2. 6H2O (0.291 g, 1 mmole), trans-cinnamic acid (0.148 g, 1 mmole), NaOH (0.04 g, 1 mmole) and 4,4'-bpy (0.156 g, 1 mmole) were dissolved with 10 ml of mixed solution (MeOH/H2O: 2/1) in a 20 ml Teflon-lined stainless steel reactor and heated to 120°C for 24 h. The reactor was cooled to room temperature over a period of 24 h, the reaction was filtered. The orange filtrate was kept for several weeks at room temperature. Orange crystals suitable for X-ray analysis were obtained. Note: the measured crystal is a fragment cut from a larger crystal.

Refinement top

Water hydrogen atoms were tentatively found in the difference density Fourier map and were refined with an isotropic displacement parameter 1.5 that of the adjacent oxygen atom. The O—H distances were restrained to be 0.9 Å within a standard deviation of 0.01 with Uiso(H) = 1.5 Ueq(O) and the H···H contacts were restraint to 1.40 Å with a standard deviation of 0.02. A l l other Hydrogen atoms were placed in calculated positions with C —H distances of 0.93–0.96 Å for aromatic H atoms with Uiso(H) =1.2 Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
