In the title complex, {[Co(NCS)2(C10H8N2)(H2O)2]·C10H8N2}n, the CoII ion is located on an inversion centre and is coordinated by two N atoms from the two 4,4′-bipyridine ligands, two O atoms from the water molecule, and two N atoms from two isothiocyanate ions in a distorted octahedral environment. In the crystal, the coordinated water molecules, isothiocyanate ions and solvent 4,4′-bipyridine molecules are linked by O—H⋯S and O—H⋯N hydrogen bonds into layers parallel to the ab plane.

A mixture of Co(CH3COO)2(0.5 mmol), 4,4'-bipy (0.5 mmol and H2O (10.00 ml), was placed in a Parr Teflon-lined stainless steel vessel (10 ml), and then the vessel was sealed and heated at 393 K for 3 d. After the mixture was slowly cooled to room temperature, a few red crystals of [Co(4,4'-bipy)(NCS)2(OH2)2].(4,4'-bipy) were obtained.
H atoms of water molecule were located in a difference map and refined with O—H distance restraints of 0.82 (3)) Å, and Uiso(H) = 1.5Ueq(O). Other H atoms bonded to C atoms were introduced at calculated positions and refined using a riding model, with Uiso(H) = 1.2Ueq(C), and C—H distances of 0.93 Å.

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. |

For 2-D MnII and 1-D CuII complexes constructed from 4,4'-bipy see: Yang et al. (2008) and Zhou, et al. (2008). The compound of [Co(4,4'-bipy)(NCS)2(OH2)2].(4,4'-bipy) were reported (Lu, et al. 1997) but the polymeric compound has not been synthesized, so far. Herein, we report the crystal structure of a novel polymeric compound, {[Co(4,4'-bipy)(NCS)2(OH2)2].(4,4'-bipy)}n. The CoII ion is coordinated by two N atoms from 4,4'-bipy ligand, two N atoms from isothiocyanate ions, and two O atoms from two water molecule in a distorted octahedral geometry (Fig. 1, Table 1). O(1), N(2), O(1)i and N(2)i[symmetry code: -1 + x, y, z] lie in the equatorial plane, with the O(1)—N(2)—O(1)i—N(2)i torsional angle of 0.02 (11)°, while the Co atom deviates from the equatorial plane by 0.051 Å. N(5), N(5)i atoms occupy the axial sites, which are strictly linear due to a symmetry opeartion. The bond lengths and angles of the title complex are similar to the compound {[Co(4,4'-bipy)(ambdc)(OH2)2](4,4'-bipy)(DMF)}n (He et al.,2006). In the crystal packing of (l) are linked by O—H···S and O—H···N hydrogen bonds (Table 2, Fig. 2).
