(Received 3 June 2013; accepted 5 June 2013; online 15 June 2013)

In the polymeric title compound, [Zn(C7H4ClO2)2(H2O)]n, the ZnII cation is located on a twofold rotation axis and is coordinated by carboxylate O atoms of four monodentate chloro­benzoate anions and by one water mol­ecule, located on a twofold rotation axis, in a distorted square-pyramidal geometry. In the anion, the carboxyl­ate group is twisted away from the attached benzene ring by 44.16 (11)°. The chloro­benzoate anion bridges ZnII cations, forming polymeric chains running along the c-axis direction. O—H⋯O hydrogen bonds between coordinating water mol­ecules and carboxyl­ate groups link adjacent chains into layers parallel to the bc plane.

Comment top

The structural functions and coordination relationships of the arylcarboxylate ion in transition metal complexes of benzoic acid derivatives change depending on the nature and position of the substituent groups on the benzene ring, the nature of the additional ligand molecule or solvent, and the medium of the synthesis (Nadzhafov et al., 1981; Shnulin et al., 1981). Transition metal complexes with biochemically active ligands frequently show interesting physical and/or chemical properties, as a result they may find applications in biological systems (Antolini et al., 1982). Some benzoic acid derivatives, such as 4-aminobenzoic acid, have been extensively reported in coordination chemistry, as bifunctional organic ligands, due to the varieties of their coordination modes (Chen & Chen, 2002; Amiraslanov et al., 1979; Hauptmann et al., 2000). The title compound was synthesized and its crystal structure is reported herein.

The asymmetric unit of the title compound, (I), contains one-half ZnII cation, one chlorobenzoate (CB) anion and one-half water molecule (Fig. 1). In the crystal, two CB anions bridge adjacent ZnII cations, forming a polymeric chain running along the c axis, while the water molecule coordinate in a monodentate manner to the ZnII cation, completing the distorted square-pyramidal geometry (Fig. 2). As a result of the CB anions bridging of the adjacent ZnII cations, an eight-membered ring is formed where the distances between the symmetry related atoms, Zn1···Zn1b [4.3798 (3) Å], O1···O1b [3.020 (2) Å], O2···O2b [4.337 (2) Å] and C1···C1b [3.975 (2) Å] [symmetry code: (b) - x, - y, 1 - z], may reflect its size.

The crystal structures of some benzoate containing polymeric complexes of MnII, ZnII, PbII and CoII ions, [Mn2(C8H7O2)4(C10H14N2O)2(H2O)]n (Hökelek et al., 2010a), [Mn(C7H4FO2)2(H2O)2]n (Necefoğlu et al., 2011), [Zn(C8H5O3)2(C6H6N2O)]n (Hökelek et al., 2009), [Pb(C8H7O2)2(C6H6N2O)]n (Hökelek et al., 2010b), {[Pb(C9H9O2)2(C6H6N2O)].H2O}n (Hökelek et al., 2011), {[Pb(C7H5O3)2(C6H6N2O)].H2O}n (Zaman et al., 2012) and [Co(C7H4IO2)2(H2O)2]n (Aydın et al., 2012) have also been reported.

In the title compound, the four O atoms (O1, O1a, O2b and O2c) [symmetry codes: (a) - x, y, 1/2 - z, (b) - x, - y, 1 - z, (c) x, - y, - 1/2 + z] in the equatorial plane around the ZnII cation form a distorted square-planar arrangement, while the distorted square-pyramidal geometry is completed by the water O atom (O3) in the axial position. The near equalities of the C1—O1 [1.260 (2) Å] and C1—O2 [1.258 (2) Å] bonds in the carboxylate group indicate delocalized bonding arrangement, rather than localized single and double bonds. The average Zn—O bond length is 2.0636 (12) Å (for benzoate oxygens) and 1.9664 (19) Å (for water oxygen) (Table 1) close to standard values (Allen et al., 1987). The Zn atom is displaced out of the mean-plane of the carboxylate group (O1/C1/O2) by 1.3998 (1) Å. Atoms Cl1, C1 and O1 are -0.0897 (7), -0.0181 (16) and -0.2341 (12) Å away from the mean-plane of the adjacent benzene ring, respectively. The dihedral angle between the planar carboxylate group (O1/C1/O2) and the adjacent benzene ring A (C2—C7) is 44.16 (11)°.

In the crystal, strong O—H···O hydrogen bonds (Table 2) link the water hydrogens to the carboxylate oxygens in the polymeric chains (Fig. 3).

Experimental top

The title compound was prepared by the reaction of ZnSO4.H2O (0.89 g, 5 mmol) in H2O (50 ml) with sodium 3-chlorobenzoate (1.79 g, 10 mmol) in H2O (100 ml) at room temperature. The mixture was filtered and set aside to crystallize at ambient temperature for one week, giving colorless single crystals.

Refinement top

Atom H31 (for H2O) was located in a difference Fourier map and was refined freely. The C-bound H-atoms were positioned geometrically with C—H = 0.93 Å for aromatic H-atoms, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

Structure description top

The structural functions and coordination relationships of the arylcarboxylate ion in transition metal complexes of benzoic acid derivatives change depending on the nature and position of the substituent groups on the benzene ring, the nature of the additional ligand molecule or solvent, and the medium of the synthesis (Nadzhafov et al., 1981; Shnulin et al., 1981). Transition metal complexes with biochemically active ligands frequently show interesting physical and/or chemical properties, as a result they may find applications in biological systems (Antolini et al., 1982). Some benzoic acid derivatives, such as 4-aminobenzoic acid, have been extensively reported in coordination chemistry, as bifunctional organic ligands, due to the varieties of their coordination modes (Chen & Chen, 2002; Amiraslanov et al., 1979; Hauptmann et al., 2000). The title compound was synthesized and its crystal structure is reported herein.

The asymmetric unit of the title compound, (I), contains one-half ZnII cation, one chlorobenzoate (CB) anion and one-half water molecule (Fig. 1). In the crystal, two CB anions bridge adjacent ZnII cations, forming a polymeric chain running along the c axis, while the water molecule coordinate in a monodentate manner to the ZnII cation, completing the distorted square-pyramidal geometry (Fig. 2). As a result of the CB anions bridging of the adjacent ZnII cations, an eight-membered ring is formed where the distances between the symmetry related atoms, Zn1···Zn1b [4.3798 (3) Å], O1···O1b [3.020 (2) Å], O2···O2b [4.337 (2) Å] and C1···C1b [3.975 (2) Å] [symmetry code: (b) - x, - y, 1 - z], may reflect its size.

The crystal structures of some benzoate containing polymeric complexes of MnII, ZnII, PbII and CoII ions, [Mn2(C8H7O2)4(C10H14N2O)2(H2O)]n (Hökelek et al., 2010a), [Mn(C7H4FO2)2(H2O)2]n (Necefoğlu et al., 2011), [Zn(C8H5O3)2(C6H6N2O)]n (Hökelek et al., 2009), [Pb(C8H7O2)2(C6H6N2O)]n (Hökelek et al., 2010b), {[Pb(C9H9O2)2(C6H6N2O)].H2O}n (Hökelek et al., 2011), {[Pb(C7H5O3)2(C6H6N2O)].H2O}n (Zaman et al., 2012) and [Co(C7H4IO2)2(H2O)2]n (Aydın et al., 2012) have also been reported.

In the title compound, the four O atoms (O1, O1a, O2b and O2c) [symmetry codes: (a) - x, y, 1/2 - z, (b) - x, - y, 1 - z, (c) x, - y, - 1/2 + z] in the equatorial plane around the ZnII cation form a distorted square-planar arrangement, while the distorted square-pyramidal geometry is completed by the water O atom (O3) in the axial position. The near equalities of the C1—O1 [1.260 (2) Å] and C1—O2 [1.258 (2) Å] bonds in the carboxylate group indicate delocalized bonding arrangement, rather than localized single and double bonds. The average Zn—O bond length is 2.0636 (12) Å (for benzoate oxygens) and 1.9664 (19) Å (for water oxygen) (Table 1) close to standard values (Allen et al., 1987). The Zn atom is displaced out of the mean-plane of the carboxylate group (O1/C1/O2) by 1.3998 (1) Å. Atoms Cl1, C1 and O1 are -0.0897 (7), -0.0181 (16) and -0.2341 (12) Å away from the mean-plane of the adjacent benzene ring, respectively. The dihedral angle between the planar carboxylate group (O1/C1/O2) and the adjacent benzene ring A (C2—C7) is 44.16 (11)°.

In the crystal, strong O—H···O hydrogen bonds (Table 2) link the water hydrogens to the carboxylate oxygens in the polymeric chains (Fig. 3).

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 > 2sigma(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.
