In the title polymer, {[Co(C14H10N2O4)(H2O)]·3.5H2O}n, the Co2+ ion is coordinated by three carboxylate O atoms from two 5-[(pyridin-2-ylmethyl)amino]isophthalate anions, two N atoms from a (pyridin-2-ylmethyl)amino group and an O atom from a water molecule, furnishing a distorted CoO4N2 octahedral geometry. Each anion acts as a μ3-bridge, linking cobalt ions into a two-dimensional layer parallel to (100). The also contains three and a half solvent water molecules, which could not be modeled. Therefore, the diffraction contribution of the solvent water molecules was removed by the subroutine SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148–155]. The is stabilized by O—H⋯O hydrogen bonds in which the coordinated water molecule acts as donor and the carboxylate O atoms as acceptors.

A mixture of cobalt nitrate hexahydrate (58.2 mg, 0.2 mmol), 5-(pyridin-2-ylmethyl)aminoisophthalic acid (54.4 mg, 0.2 mmol), and 3 ml N,N-dimethylformamide in H2O (12 ml) was sealed in a 16 ml Teflon-lined stainless steel container and heated to 373 K for 3 days. After cooling the container to the room temperature, red block crystals of the title complex were obtained.
The hydrogen atoms bonded to C atoms were included in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 and 0.97 Å for aryl and methylene H-atoms with Uiso(H) = 1.2Ueq(C). The hydrogen atoms bonded to N1 and O5 were located from a difference Fourier map and fixed at those positions with Uiso(H) = 1.2Ueq(N or O)]. The structure contains three and a half molecules of water of hydration, which could not be modeled as discrete atomic sites. We employed SQUEEZE in PLATON (Spek, 2009) to remove the diffraction contribution of the solvent water molecules.
5-(Pyridin-2-ylmethyl)aminoisophthalic acid possesses some peculiar features in the assembly of coordination compounds due to its unique molecular structure. Herein, we report the
of the title complex. The consists of one cobalt ion, one 5-(pyridin-2-ylmethyl)aminoisophthalate anion, one coordinated water molecule, and 3.5 lattice water molecules. However, the solvent water molecules could not be modeled as discrete atomic sites. We employed SQUEEZE subroutine in PLATON (Spek, 2009) to exclude the diffraction contribution of the solvent water molecules.In the title polymer, each Co ion is coordinated by three carboxylate O atoms from two different 5-(pyridin-2-ylmethyl)aminoisophthalate anions, two N atoms from (pyridin-2-ylmethyl)amino group and one O atom from a coordinated water molecule, to furnish a distorted CoO4N2 octahedral geometry (Fig. 1). Each anion acts as a µ3-bridge, linking cobalt ions to form a two-dimensional layer. In the
there exist O—H···O hydrogen bonds (Table 1). Coordinated water molecule and carboxylate oxygen atoms act as donors or acceptors in the formation of these hydrogen bonding interactions.For related structures, see: Kuai et al. (2011).

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. |

5-(Pyridin-2-ylmethyl)aminoisophthalic acid possesses some peculiar features in the assembly of coordination compounds due to its unique molecular structure. Herein, we report the crystal structure of the title complex. The asymmetric unit consists of one cobalt ion, one 5-(pyridin-2-ylmethyl)aminoisophthalate anion, one coordinated water molecule, and 3.5 lattice water molecules. However, the solvent water molecules could not be modeled as discrete atomic sites. We employed SQUEEZE subroutine in PLATON (Spek, 2009) to exclude the diffraction contribution of the solvent water molecules.
In the title polymer, each Co ion is coordinated by three carboxylate O atoms from two different 5-(pyridin-2-ylmethyl)aminoisophthalate anions, two N atoms from (pyridin-2-ylmethyl)amino group and one O atom from a coordinated water molecule, to furnish a distorted CoO4N2 octahedral geometry (Fig. 1). Each anion acts as a µ3-bridge, linking cobalt ions to form a two-dimensional layer. In the crystal structure, there exist O—H···O hydrogen bonds (Table 1). Coordinated water molecule and carboxylate oxygen atoms act as donors or acceptors in the formation of these hydrogen bonding interactions.
