The title complex, [Zn2(C12H6O4)2(C10H8N2)2(H2O)2]·4H2O, is a binuclear complex with two independent ZnII ions in a slightly disorted trigonal bipyramidal environment, coordinated by one aqua ligand, two naphthalene-1,8-dicarboxyl­ate ligands and one 2,2′-bipyridine ligand. ππ Inter­actions [centroid–centroid distance of 3.8489 (5) Å] and O—H⋯O hydrogen bonds connect the mol­ecules, forming a three-dimensional structure.

As known, naphthyl-containing aromatic multicarboxylato ligands are versatile building blocks to construct interesting structures with potential properties due to their variety of bridging abilities. In our former work, 1,8-naphthalenecarboxylic anhydride, which is hydrolyzed to naphthalene-1,8-dicarboxylate ligand in hydrothermal condition, is employed as starting material to prepare coordination polymers (Wen et al., 2007; He et al., 2007; Wen et al., 2008; Feng et al., 2008).

The structure of (I) (Fig.1) is a zero-dimensional molecule. Each central ZnII ion is in a slightly distorted trigonal bipyramid environment, coordinated by one aqua ligand, two naphthalene-1,8-dicarboxylate ligands and one 2,2'-bipyridine ligand. Two naphthalene-1,8-dicarboxylate ligands link two five-coordinated ZnII ions to form a eighteen-membered ring. O—H···O hydrogen bonds link independent molecules to form a two-dimensional network. Weak π-π interactions with centroid-centroid distance of 3.849Å connect the layers to yield a three-dimensional structure.

Experimental top

Zn(CH3COO)2.2H2O (0.1108 g, 0.5 mmol), 1, 8-naphthalenecarboxylic anhydride (0.0996 g, 0.5 mmol), NaOH (0.0405 g, 1 mmol), 2,2'-bipy (0.0385 g, 0.25 mmol) and H2O-ethanol (2:1, 15 ml) was sealed in a 25 ml stainless-steel reactor with a Teflon liner and was heated at 433 K for 3 d. On completion of the reaction, the reactor was cooled slowly to room temperature and the mixture was filtered, giving pink single crystals suitable for X-ray analysis in yield 39%.

Refinement top

The carbon-bound H-atoms were positioned geometrically and included in the refinement using a riding model [C—H 0.93 Å Uiso(H) = 1.2Ueq(C)]. The water H atoms were located from different maps and their positions were refined isotropically, with O—H distances fixed by O—H = 0.85 (2) Å and H···H = 1.30 (2) Å, their displacement parameters were set to 1.5Ueq(O).

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.
