Source of material

A mixture of H2epda (5-ethylpyridine-2,3-dicarboxylic acid) (0.2 mmol, 39.1 mg), Bip (4,4′-bis(imidazolyl)biphenyl) (0.1 mmol, 28.7 mg), Zn(OAc)2 · H2O (0.1 mmol, 21.9 mg), H2O (3.0 mL), CH3CH2OH (3.0 mL) and KOH (0.1 mmol) was sealed in a 23 mL Teflon-lined autoclave, heated to 393 K for 6 days, and then slowly cooled down to room temperature for crystallization. Colourless block-shaped crystals of the title compound were obtained.

Experimental details

The OH groups were idealized and refined using rigid groups allowed to rotate about the O—H bond (AFIX 147 option of the SHELX-2013 program [9]). Hydrogen atoms of the water molecule were allowed to ride on the parent O atoms (AFIX 3 option of the SHELX-2013 program [9]). The coordinates of the aromatic hydrogen atoms as well as the hydrogen atoms of CH2 groups and methyl groups were idealized and refined using a riding model (AFIX 43, AFIX 23 and AFIX 137 option of the SHELX-2013 program [9]).

Discussion

As an important branch in the field of supramolecular chemistry and crystal engineering, supramolecular coordination polymeric networks have stimulated the interests of chemists over the past few decades for their high impact in the domain such as catalysis, molecule storage, ion-exchange, separations, magnetism, and photoactive materials [1–6]. It is well known that coordination ability of the organic ligands is among the very key factors for the assembly of topologically new MOFs with improved functional properties as well as N-containing auxiliary ligands can modify the structures and properties of the resulting metal-organic complexes [7, 8]. We report herein the binding of H2epda (H2epda = 5-ethylpyridine-2,3-dicarboxylic acid) and bip (4,4′-bis(imidazolyl)biphenyl ligands to Zn(II) centers forming a complex.

Single-crystal X-ray analysis shows that the asymmetric unit of title structure contains one crystallographically independent Zn(II) center two 3-carboxy-5-ethylpyridine-2-carboxylate ligands one half bip molecule and one coordinated water molecule (see the figure). The Zn1 atom resides in a distorted octahedral environment [ZnO3N3] with the basal plane defined by O1 and O5 atoms from two hepda anion and O9W from one coordination water molecule as well as N3 from one bip molecule. The apical site is occupied by N1 and N2 atoms from two hepda anions. The auxiliary bip ligands bridged two zinc octahedra with the Zn⋯—Zn separation of 17.9620(7) Å. All the Zn–N and Zn–O bond lengths are in the range of 2.086(2)–2.091(2) Å and 2.065(2)–2.293(2) Å, respectively. Each hepda anion chelate only one Zn(II) metal centers through one nitrogen atom of the pyridine ring and an oxygen atom of the α-carboxyl group to form five-membered rings, and the β-carboxyl group remains uncoordinated. Consequently, a dizinc complex is obtained (see the figure).

There are intramolecular hydrogen bonds between the coordinated α-carboxylate O atoms and the uncoordinated β-carboxylate O atoms in both hepda ligands (O3–H3⋯O2 with the bond distance of 2.409(4) Å and bond angle of 178.9° as well as O7–H7⋯O6 with the bond distance of 2.398(4) Å and bond angle of 177.2°). There are further hydrogen bonds between coordinated water ligands and the coordinated β-carboxylate O atoms from another binuclear unit (O9W–H2W⋯O8B with the bond distance of 2.695(4) Å and bond angle of 177.2° as well as O9W–H1W⋯O4C with the bond distance of 2.723(3) Å and bond angle of 168.9°), which link the adjacent binuclear unit to form a layered structure.
