The CoII ion in the title complex, [Co2(C4H5O2)4(C15H13N5)2]·2H2O, has a distorted square-planar coordination formed by the bridging bidentate N,N′-di-4-pyridylpyridine-2,6-diamine (dapmp) ligands and two monodentate carboxylate groups from methacrylates. Two dapmp ligands bridge two Co atoms, forming a dinuclear complex arranged around an inversion centre. N—H⋯O and O—H⋯O hydrogen bonds involving the solvent water molecule result in the formation of a three-dimensional network. The aliphatic moiety of one of the methacrylate groups is disordered over two positions with fixed occupancies of 0.67 and 0.33.

dapmp (0.05 g, 0.18 mmol), Co(CH3COO)2 (0.035 g, 0.16 mmol), methacrylic acid (0.032 g, 0.15 mmol) and NaOH (1M, 0.5 mL) were added distilled water(15 mL), the mixture was heated for fifty hours under reflux. during the process stirring and influx were required. The resultant was kept at room temperature, two weeks later some single crystals of the size suitable for X-Ray diffraction measurement.
All H atoms attached to C atoms and N atom were fixed geometrically and treated as riding with C—H = 0.98 Å (methyl) or 0.97 Å (methylene) and N—H = 0.86 Å with Uiso(H) = 1.2Ueq(C or N). H atoms of water molecule were located in difference Fourier maps and included in the subsequent
using restraints (O-H= 0.82 (1)Å and H···H= 1.38 (2)Å) with Uiso(H) = 1.5Ueq(O). In the last stage of they were treated as riding on their parent O atom.The C atoms of one of the methacrylate group are disordered. The ratio of the occupancy factors of each component was determined to be 0.33/0.67. The two components were refined using the tools available in SHELXL-97 (PART and SAME instructions). Each corresponding C atoms were anisotropically refined using EADP restraints.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

Bridging bis(amidopyridine) ligands have been widely explored in coordination chemistry for building various novel structural architectures and functional solid materials. Besides their diverse coordination modes, amide groups of ligands have proved to be useful in self-assembly, since they give predictable patterns of hydrogen bonding that can add extra dimensionality and helicity to the supramolecular structures (Burchell, et al., 2006; Patra et al., 2004). The 2,4-di(2-aminopyridine)-6-methypyrimidine (dapmp) ligand is a versatile ligand like but with more diversity than terpyridine (tpy). The modified title ligand and its complexes have been reported (Thorsten et al., 2004). In this paper, we report here the synthesis and crystal structure of the title compound (I).
The Co(II) atom in the title complex, has a square coordination formed by two N atoms of two bridging dapmp ligands and two O atoms of two monodentate carboxylate groups from methacrylates. The bridging dapmp ligands bridge two Co atoms forming a dinuclear complex arranged around inversion center (Fig.1). The average Co—N bond length of 2.006 Å is close to the values observed in related complexes (Liu et al., 2008).
The occurence of N-H···O and O-H···O hydrogen bondings involving the solvent water molecule results in the formation of a three dimensionnal network (Table 1).
