(Received 15 November 2010; accepted 28 November 2010; online 11 December 2010)

In the centrosymmetric binuclear title compound, [Ni2(C15H8O7)2(H2O)6], the NiII ion is in a distorted octa­hedral coordination geometry with O6 donors, three from three water mol­ecules, the others from three carboxylate groups of two ligands. Extensive O—H⋯O hydrogen bonding connects the mol­ecules into a three-dimensional supra­molecular structure.

Comment top

In the field of supramolecular chemistry and crystal engineering, the design and assembly of metal-organic coordination polymers with appealing structures and properties have stimulated interests of chemists (Evans et al., 1999). The hydrogen bonding interaction often leads to complicated spramolecular structure (Li et al., 2008).

As shown in Fig.1, compound I is a new binuclear neutral complex with a shuttle molecular configuration. The two Ni(II) ions locate in the middle of this molecule. Ni(II) atom is coordinated in a octahedral coordination sphere The bond lengths of Ni—O are similar with the values in those complexes containing Ni—O sgment (Wang et al., 2010). There are rich hydrogen bonding interaction O—H···O in this compound, giving a three-dimensional supramolecular structure.

H3L4 (0.0302 g, 0.1 mmol), Ni(OAc)2.4H2O (0.0498 g, 0.2 mmol), and H2O (15 ml) was sealed in 25 ml Teflon-lined stainless steel reactor and heated to 120 oC. Green block-shaped crystals suitable for X-ray diffraction analysis were separated by filtration with the yield of 37%

Refinement top

All H-atoms bound to carbon were refined using a riding model with distance C—H = 0.93 Å, Uiso = 1.2Ueq (C) for aromatic atoms. The distance of O—H of water molecule has been restrained using the 'DFIX' command as 0.85Å with the deviation of 0.01.

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.
