In the title compound, [Co(C9H8NO3)(C12H8N2)2(H2O)]NO3·H2O, the CoII atom is six-coordinated by a carboxylate O atom of the hippurate (Hc) anion, a water O atom and four N atoms from two 1,10-phenanthroline ligands in a distorted octahedral geometry. The uncoordinated O atom of the hippuric acid anion is involved in an intramolecular hydrogen bond to the coordinated water molecule. The crystal packing is stabilized by intermolecular O—H⋯O hydrogen bonds involving the Hc anions, the coordinated water molecule, the nitrate anion and the uncoordinated water molecule.

Hippuric acid (1.0 mmol) , Co(NO3)2.6H2 (O1.0 mmol) and 1,10-phenanthroline (2.0 mmol) were dissolved in a water-ethanol mixture(v/v=1:4; 25 ml). The obtained solution was continously stirred, and its pH was adjusted to 6–7 by 1.0 mol L-1 NaOH aqueous solution. Then the mixture was further stirred for ca 2 h at room temperature and filtered. The resultant filtrate was left to stand for slow evaporation at room temperature. Dark-red single crystals of (I) suitable for X-ray
were obtained after two weeks (yield 66%).Hydrogen atoms attached to carbon atoms and nitrogen atoms were positioned geometrically and treated as riding, with C—H = 0.93 Å, N—H = 0.86 Å, and Uiso(H) = 1.2Ueq(C or N). The hydrogen atoms of the coordination water molecules and lattice water molecules were assigned in the difference Fourier maps and refined isotropically.
Hippuric acid (Hc) is a naturally occurring carboxylic acid found in the urine of most mammals. Several decades ago, hippuric acid was testified as a good building units for metal complexes with desirable magnetic properties, due to the carboxylic group of hippuric acid can act as donor to link metal centers. To date, the synthesis, crystal structures, and related property studying of Ni(II), Fe(II), Zn(II), Cu(II) complexes based on hippuric acid have been reported (Antolini, et al., 1982; Brown, et al., 1973; Grewe, et al., 1982; Guo, Wang, Chen, et al., 2006; Guo, Chen, Wang, et al., 2006; Morelock, Good, Trefonas, Karraker et al., 1979; Morelock, Good, Trefonas, Majeste et al., 1982). Herein, we present the synthesis and
of its Co(II) complex.The title compound, (I), is a mononuclear complex, consisting of one [Co(Hc)(phen)2(H2O)]+ unit, one NO3- anion, and one crystal H2O molecule (Fig. 1). The Co(II) ion is six-coordinated by O atoms from one Hc anion and one water molecule, four N atoms of two 1,10-phen ligands in a shape of distorted octahedron. The atoms N2, N3, N5, and O4 are located in the equatorial plane whereas O2 and N4 occupy the axial positions. The bond distances and angles around Co atom reveal a distorted octahedron (bite-chelating angles are 77.2 and 77.822 °). The Hc anion acts as a monodentate ligand, with one of the carboylic oxygen atoms coordinated to the Co(II) ions, while the amide O and imine N atoms remain uncoordinated.
The coordinated water molecule and the crystal water molecule donate H atom to the nitrate anion and to the Hc anion ligand to form O—H···O hydrogen bonds. In addition, the imine group of the Hc anion also donate H atom to the nitrate to form N—H···O hydrogen bonds (Table 1, Fig. 2).

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. |

Hippuric acid (Hc) is a naturally occurring carboxylic acid found in the urine of most mammals. Several decades ago, hippuric acid was testified as a good building units for metal complexes with desirable magnetic properties, due to the carboxylic group of hippuric acid can act as donor to link metal centers. To date, the synthesis, crystal structures, and related property studying of Ni(II), Fe(II), Zn(II), Cu(II) complexes based on hippuric acid have been reported (Antolini, et al., 1982; Brown, et al., 1973; Grewe, et al., 1982; Guo, Wang, Chen, et al., 2006; Guo, Chen, Wang, et al., 2006; Morelock, Good, Trefonas, Karraker et al., 1979; Morelock, Good, Trefonas, Majeste et al., 1982). Herein, we present the synthesis and crystal structure of its Co(II) complex.
The title compound, (I), is a mononuclear complex, consisting of one [Co(Hc)(phen)2(H2O)]+ unit, one NO3- anion, and one crystal H2O molecule (Fig. 1). The Co(II) ion is six-coordinated by O atoms from one Hc anion and one water molecule, four N atoms of two 1,10-phen ligands in a shape of distorted octahedron. The atoms N2, N3, N5, and O4 are located in the equatorial plane whereas O2 and N4 occupy the axial positions. The bond distances and angles around Co atom reveal a distorted octahedron (bite-chelating angles are 77.2 and 77.822 °). The Hc anion acts as a monodentate ligand, with one of the carboylic oxygen atoms coordinated to the Co(II) ions, while the amide O and imine N atoms remain uncoordinated.
The coordinated water molecule and the crystal water molecule donate H atom to the nitrate anion and to the Hc anion ligand to form O—H···O hydrogen bonds. In addition, the imine group of the Hc anion also donate H atom to the nitrate to form N—H···O hydrogen bonds (Table 1, Fig. 2).
