Abstract top

In the title compound, [Ni(H2O)6](C16H12O6)·H2O, the NiII cation is located on a mirror plane and is coordinated by six water molecules, two of which are also located on the mirror plane, in a distorted octahedral geometry. The 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoate anion is centrosymmetric with the mid-point of the central ethane C-C bond located on an inversion center. The uncoordinated water molecule is located on a mirror plane. Extensive O-H...O hydrogen bonding is present in the crystal structure.

Comment top

Metal-organic networks constructed by benzene-multicarboxylato ligands, have attracted a great deal of recent interest (Wisser et al., 2008; Sun et al., 2006; Janiak et al., 2003). Benzene-1,4-dicarboxylate with a 180° angle between the two carboxylic groups, can form short bridges via one carboxylato end and long bridges via the benzene ring, leading to a great variety of novel structures (Carton et al., 2007; Manna et al., 2007; Banerjee et al., 2005). Considering that in mind, our group select a derivative of the benzene-1,4-dicarboxylate named 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoate to react with Ni(NO3)2 to obtain novel metal-organic complex.

In figure 1, the title compound (C16H12O6)[Ni6H2O].H2O is obtained under hydrothermal condition, which comprises one 4,4'-(1,2-dihydroxyethane-1,2 -diyl)dibenzoate anion, one [Ni6H2O]2+ cation and a solvent water molecule, of which the [Ni6H2O]2+ cation and solvent water is lying on mirror planes, and the anion is locating on an inversion center. the two carboxyl groups of the ligand are total deprotonated, indicated by a difference of the bond lengths, which are also lying in the plane of the benzene rings. and the NiII center is coordinated by six water molecules instead of the 4,4'-(1,2-dihydroxyethane- 1,2-diyl)dibenzoate ligand. the O—H···O hydrogen bonding interactions between the carboxyl and hydroxyl of the ligands build an infinite chain along a axis. the chains, [Ni6H2O]2+ cations and solvent water molecules was further linked by additional O—H···O hydrogen bonds, forming a three-dimensional network.

Experimental top

A solution of 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoic acid (0.5 mol, 0.15 g) and Ni(NO3)2 (0.5 mol, 0.14 g) and 20 ml water was stirred continuously, whose pH was adjusted to 7 by the addition of NaOH solution. The solution was then sealed in an autoclave equipped with a Teflon liner (20 ml) and heated at 373 K for 4 days. Crystals of the title compound were obtained by slow evaporation at room temperature.

Refinement top

H atoms bound to C atoms were placed at calculated positions and were treated as riding on the parent atoms with C—H = 0.93 Å (aromatic) and 0.98 Å (CH) and with Uiso(H) = 1.2 Ueq(C). H atoms of hydroxyl group and water molecules were located in a difference Fourier map and refined as riding with O—H = 0.85+_0.01 Å and Uiso(H) = 1.5Ueq(O) for water O atoms and O—H = 0.89±0.01 Å and 1.2 Ueq(O) for hydroxyl.

Special details top

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.
