The Zn atom in the title compound, [Zn(C7H5O2)2(C12H8N2)(H2O)], is five-coordinate in a distorted trigonal–bipyramidal coordination environment involving two O atoms of two monodentate benzoates, two N atoms of a 1,10-phenanthroline molecule and one O atom of a water molecule. The axial positions are occupied by a carboxylate O atom from the benzoate ligand and an N atom from the 1,10-phenanthroline ligand [N—Zn—O = 146.90 (7)°]. The water molecule forms an intramolecular O—H⋯O hydrogen bond; an intermolecular O—H⋯O hydrogen bond gives rise to a dimer.

C4H6ZnO4.2H2O(0.2195 g,1 mmol), benzoic acid(0.2442 g,2 mmol), NaOH(0.08 g;2 mmol),1,10-phenanthroline (0.1802 g,1 mmol) were added to a mixture of water (15 ml) and ethanol (10 ml). The resulting mixture was stirred at 70 for 4 h and fltered off. The filtrate was allowed to stand at room temperature and slow evaporation afforded colorless block crystals of the complex(Yield 65%).Elemental analysis: found C,61.69;H,3.98;N,5.57;calc for C26H20N2O5Zn:C,61.73; H,3.99;N,5.54(%).
H atoms on C atoms were positioned geometrically refined using a riding model with C—H=0.93–0.96ÅandUiso(H) = 1.2Ueq(C),The water H atoms were located in difference density Fourier maps and refined using a riding model with O—H=0.82Åand Uiso(H) = 1.5Ueq(C).
In the present study, we report the synthesis and
of the title complex (I). The biological activity of (I) against common bacterial strains is to be investigated. Selected geometric parameters are listed in Table 1. As shown in Fig. 1, (I) is a mononuclear neutral zinc(II) complex in which the carboxylate group exhibits a monodentate coordination mode. By contrast, in the mononuclear zinc complex of diaquabis (benzoato)zinc(II), each carboxylate ligand forms a primary and a secondary Zn—O bond (Necefoglu et al., 2001). The Zn ion in (I) is coordinated by two O atoms from two monodentate benzoate ligands (O1 and O3), two N atoms from the 1,10-phenanthroline ligand (N1 and N2) and one O atom from the water molecule (O5), and exhibits distorted trigonal-bipyramidal coordination. The trigonal base plane is defined by atoms N1, O1 and O5, and atoms O3 and N2 occupy the axial positions [O3—Zn—N2 =146.91 (5)°]. A strong intermolecular hydrogen bond exists, involving uncoordinated atom O4 of the carboxylate group as an acceptor and atom O5 as a donor (Table 2), resulting in the formation of a dimer (Fig. 2). There is also an intramolecular hydrogen bond between the other H atom of the water molecule and uncoordinated atom O2 of the other carboxylate group (Table 2).For a related structure, see: Necefoglu et al. (2001).

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. |

In the present study, we report the synthesis and crystal structure of the title complex (I). The biological activity of (I) against common bacterial strains is to be investigated. Selected geometric parameters are listed in Table 1. As shown in Fig. 1, (I) is a mononuclear neutral zinc(II) complex in which the carboxylate group exhibits a monodentate coordination mode. By contrast, in the mononuclear zinc complex of diaquabis (benzoato)zinc(II), each carboxylate ligand forms a primary and a secondary Zn—O bond (Necefoglu et al., 2001). The Zn ion in (I) is coordinated by two O atoms from two monodentate benzoate ligands (O1 and O3), two N atoms from the 1,10-phenanthroline ligand (N1 and N2) and one O atom from the water molecule (O5), and exhibits distorted trigonal-bipyramidal coordination. The trigonal base plane is defined by atoms N1, O1 and O5, and atoms O3 and N2 occupy the axial positions [O3—Zn—N2 =146.91 (5)°]. A strong intermolecular hydrogen bond exists, involving uncoordinated atom O4 of the carboxylate group as an acceptor and atom O5 as a donor (Table 2), resulting in the formation of a dimer (Fig. 2). There is also an intramolecular hydrogen bond between the other H atom of the water molecule and uncoordinated atom O2 of the other carboxylate group (Table 2).
