Abstract top

The title compound, [Zn(C8H7O2)(C10H8N2)2](C8H7O2)·C8H8O2·2H2O, is comprised of a Zn2+ cation, two 2,2'-bipydine (bipy) ligands and one 3-methylbenzoate anion (L-) together with one uncoordinating L- anion, one uncoordinating HL molecule and two lattice water molecules. The ZnII atom is coordinated by four N atoms of two bipy ligands and two O atoms from one L- ligand in a distorted octahedral geometry. Pairs of centrosymmetrically related complex molecules form dimers via slipped [pi]-stacking interactions between bipy ligands with an interplanar distance of 3.470 (4) Å. The dimers are linked into supramolecular chains along [111], via C-H...O hydrogen bonds. The uncoordinated L- anions, HL molecules and water molecules are connected with each other via O-H...O hydrogen bonds, forming chains between the metal complex chains and binding them together via C-H...O contacts. The resulting layers parallel to (010) are further assembled into a three-dimensional supramolecular architecture through additional C-H...O interactions.

Comment top

In recent years, the design and synthesis of metal-organic frameworks (MOFs) have attracted considerable attention due to their intriguing topological structures (Chen et al., 2010) and potential applications in gas storage and separation, magnetism, luminescence, and catalysis (Bettencourt-Dias et al., 2006; Liu et al., 2006; Xu et al., 2010; Xu et al., 2011). Our interest in self-assemblies of Zn2+ ions and 2,2'-bipyridine (bipy) with 3-methylbenzoic acid (HL = m-CH3-C6H4COOH), led to the preparation of [Zn(C10H8N2)2(C8H7O2)](C8H7O2).(C8H8O2).2H2O.

The asymmetric unit contains a Zn2+ ion complexed by two 2,2'-bipydine ligands and one 3-methylbenzoate anion (L- = m-CH3-C6H4COO-) together with one uncoordinated L- anion, one uncoordinated HL molecule and two lattice water molecules. The Zn ion is coordinated by four nitrogen atoms (N1, N2, N3, N4) of two bipy ligands and two oxygen atoms (O1, O2) from one L- ligand in a tetragonally distorted octahedral geometry (Fig.1). The ligating atoms form a ZnN4O2 coordination environment with one carboxylate O2 atom, one pyridyl N3 atom in the axial positions and the other pyridyl N atoms and the other carboxylate O1 atom at the corners of the basal plane. The Cu-O and Cu-N bond lengths in the basal plane are in the range 2.114 (3) to 2.129 (3) Å and are slightly shorter than the axial Cu-O and Cu-N bond lengths (2.138 (3) and 2.308 (3) Å). Around the Zn2+ion the cisoid bond angles fall in the range 59.27 (9)-103.38 (10)°, and the transoid ones are 147.48 (10) and 171.36 (10)° thus exhibiting substantial deviations from 90° and 180° for an ideal octahedral geometry. The above observation indicates that the coordination geometry is a 4 + 1 + 1 type.

Two centrosymmetrically-related metal complexes molecules have bipy rings which are parallel with an interplanar distance of 3.470 (4) Å suggesting a slipped π···π stacking interaction. This together with weak, pairwise C17-H17A···O1 hydrogen bonds (Table 1) form dimeric units. Along the [111] direction the dimeric units are linked into one-dimensional supramolecular chains via pairwise C7-H7A···O2 hydrogen bonds (Table 1) and π···π stacking interactions with a distance of 3.455 (4) Å between the bipy rings which are not engaged in π···π stacking within the dimeric units (Fig.2). The uncoordinated L- anions, HL molecules and water molecules connect with each other via O–H···O hydrogen bonds to form chains between the metal complex chains and connect with the latter via C8–H18A···O8 contacts (Table 1). The resulting layers are further assembled into a three-dimensional supramolecular architecture through additional C–H···O interactions.

Experimental top

1 mL of 1M aqueous K2CO3 solution was added to an aqueous solution of ZnSO4.7H2O (0.291 g, 1 mmol) to give a white precipitate from which SO42- anions were removed by centrifugation. The white precipitate was added to 20.0 mL of a H2O/CH3OH solution (1:1 v/v) of 3-methylbenzoic acid (0.271 g, 2.0 mmol). To the resulting solution was added 2,2'-bipydine (0.310 g, 2.0 mmol) whereupon the color of the solution became a light magenta and the pH was about 5. The solution was allowed to evaporate at room temperature for several days to give colourless block-shaped crystals.

Refinement top

H atoms bonded to C were placed in calculated positions and were refined using a riding model, with Uiso(H) = 1.2 Ueq(C). H atoms attached to O were placed in locations indicated by a difference Fourier synthesis and were refined using a riding model with Uiso(H) values set at 1.2 Ueq(O).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
