A mixture of 0.27 g (1.0 mmol) NiSO4.6H2O, 1.0 ml (4.0 mmol) 2-hydroxyphosphonoacetic acid (48.0 wt %) and 0.04 g (1.0 mmol) NaF (as a mineralizer) was dissolved in 8 ml of deionized water, and then 1,4-butylenediamine was added with stirring to adjust the pH of the mixture. The mixture (pH = 4.5) was sealed in a 23 ml Teflon-lined stainless steel autoclave, and then heated at 413 K for 72 h. Colorless block crystals were obtained, washed with distilled water, and dried in air at room temperature.
During refinement, carbon bound H atoms were placed in calculated positions and allowed to ride on the parent atom, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). Oxygen bound hydrogen atoms were located from difference Fourier maps and refined with distance restraints.
Metal phosphonates have been of increasing interest in the past decade due to their potential applications in the fields of catalysis (Sharma & Clearfield, 2000), ion exchange (Clearfield, 1988), proton conductivity (Alberti et al., 1992), gas and liquid separations (Riou et al., 2000), biology (Nonglaton et al., 2004), and organic molecule sorption (Clearfield, 1998). Great efforts have been devoted to the syntheses of novel inorganic–organic hybrid materials based on metal phosphonates, which exhibit a variety of structures such as one-dimensional chains, two-dimensional layers, and three-dimensional network. To the best of our knowledge, however, reports on nickel phosphonates are rather scarce (Hix & Harris, 1998; Song et al., 1999; Modi et al., 2005).
The title compound (I) crystallizes in the orthorhombic space group Pbca. The molecular structure of (I) is shown in the Fig. 1. Each Ni atom adopts distorted octahedral coordination geometry with the six oxygen atoms from the two equivalent L3- (L = O3PCH(OH)CO2) anions and two coordinated water molecule. The values of the Ni—O bond lengths and O—Ni—O angles are in the range of 2.0329 (19)–2.0888 (19) Å and 78.81 (7)–177.88 (8) °, respectively. This architecture is further stabilized by a number of O—H···O hydrogen bonds involving the protonated hydroxyl oxygen atoms, carboxylate oxygen atoms, phosphonate oxygen atom, and coordinated water molecules (see Table 1, Table 2 and 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. |

Metal phosphonates have been of increasing interest in the past decade due to their potential applications in the fields of catalysis (Sharma & Clearfield, 2000), ion exchange (Clearfield, 1988), proton conductivity (Alberti et al., 1992), gas and liquid separations (Riou et al., 2000), biology (Nonglaton et al., 2004), and organic molecule sorption (Clearfield, 1998). Great efforts have been devoted to the syntheses of novel inorganic–organic hybrid materials based on metal phosphonates, which exhibit a variety of structures such as one-dimensional chains, two-dimensional layers, and three-dimensional network. To the best of our knowledge, however, reports on nickel phosphonates are rather scarce (Hix & Harris, 1998; Song et al., 1999; Modi et al., 2005).
The title compound (I) crystallizes in the orthorhombic space group Pbca. The molecular structure of (I) is shown in the Fig. 1. Each Ni atom adopts distorted octahedral coordination geometry with the six oxygen atoms from the two equivalent L3- (L = O3PCH(OH)CO2) anions and two coordinated water molecule. The values of the Ni—O bond lengths and O—Ni—O angles are in the range of 2.0329 (19)–2.0888 (19) Å and 78.81 (7)–177.88 (8) °, respectively. This architecture is further stabilized by a number of O—H···O hydrogen bonds involving the protonated hydroxyl oxygen atoms, carboxylate oxygen atoms, phosphonate oxygen atom, and coordinated water molecules (see Table 1, Table 2 and Fig. 2).
