4-nitrophenoxy acetic acid was prepared by nucleophilic reaction of chloroacetic acid and 4-nitrophenol under basic conditions. (Mirci, 1990). Nickel nitrate hexahydrate (0.582 g, 2 mmol) and 4-nitrophenoxy acetic acid (0.394 g, 2 mmol) were dissolved in water and the pH was adjusted to 6 with 0.01M sodium hydroxide; green crystals separated from the filtered solution after several days.
H atoms bound to C atoms were placed in calculated positions and treated as riding on their parent atoms, withwith C—H = 0.93 Å (aromatic C) or C—H = 0.93 Å (methylene C), and with Uiso(H) = 1.2Ueq(C). Water H atoms were initially located in a difference Fourier map but they were treated as riding on their parent atoms with O—H = 0.85 Å and with Uiso(H) = 1.5Ueq(O).

Complexes of 4-nitrophenoxyacetic acid and metal ions (M= Cu and Sn) have been structurally characterized (Prout et al., 1975; Tian et al., 2006). Recently, we reported the cobalt derivative (Gao et al., 2006); following this study, we report the nickel complex (I), which consists of a hexaaquanickel(II) cation, two 4-nitrophenoxyacetate anions and five lattice water molecules (Fig.1). The Ni(II) atom is six-coordinated in an octahedral environment. The two anions are approximately parallel. The cation, anion and lattice water molecules are linked by O—H···O hydrogen bonds into a three-dimensional network structure. (Table 1).

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. |

Complexes of 4-nitrophenoxyacetic acid and metal ions (M= Cu and Sn) have been structurally characterized (Prout et al., 1975; Tian et al., 2006). Recently, we reported the cobalt derivative (Gao et al., 2006); following this study, we report the nickel complex (I), which consists of a hexaaquanickel(II) cation, two 4-nitrophenoxyacetate anions and five lattice water molecules (Fig.1). The Ni(II) atom is six-coordinated in an octahedral environment. The two anions are approximately parallel. The cation, anion and lattice water molecules are linked by O—H···O hydrogen bonds into a three-dimensional network structure. (Table 1).
