Source of material
All reagents and solvents were purchased from commercial sources and used as received. An aqueous solution (15 mL) of 2,6-difluorobenzoic acid (470 mg, 3.0 mmol), NaHCO3 (240 mg, 3.0 mmol), and hexamethylenetetramine (70 mg, 0.5 mmol) was mixed with a DMF/MeOH solution (15 mL) of Cu(NO3)2⋅3H2O (450 mg, 3.3 mmol). The light blue solution was allowed to stand at room temperature to give green plate crystals within two weeks (yield 220 mg, 18%).
Experimental details
H atoms bound to C atoms were places in calculated positions and refined as riding on their parent atoms, with C—H = 0.93 Å (aromatic), C—H = 0.96 Å (methylene), C—H = 0.97 Å (ethylene), and with Uiso(H) = 1.5 Ueq(C) for methyl H atoms and 1.2 Ueq(C) for all other H atoms. The atoms of C20, F6, and F11 were disordered and the components of disordered atoms were refined isotropically.
Discussion
In the past decades, design and construction of transition metal complexes have received much attention owing to their structures as well as their potential applications [3], [4], [5]. The selection and utilization of different organic ligands is considered to be a key point for rational designing and building targeted structures. A number of multicarboxylates and neutral N-containing heterocyclic molecules are usually employed to obtain novel structures. Compared with the using of complicated organic ligands, the very simple benzoic acid/derivatives and simple heterocyclic compound hexamethylenetetramine (hmt), have been explored to a less extent. However, there are some polynuclear clusers with fascinating structures and properties constructed by benzoic derivatives have been reported [6], [7] . On the other hand, hexamethylenetetramine having four coordinating N atoms in a diamandoid-like geometry, is a versatile ligand, because it is capable of various coordination modes that span from terminal monodentate to μ2−, μ3−, or μ4-bridging mode [8]. Recently, we have reported some one-dimensional structures which were built by hmt and monocarboxylates. In the course of our study on construction new structures based on M-hmt-monocarboxylate system [9], [10], [11]. Herein, we report a new two-dimensional structure [{Cu2(dfba)4}3(hmt)2]n (dfba = 2,6-difluorobenzoate).
X-ray crystal structural analysis revealed that the asymmetric unit of the title complex is composed of three Cu2+ ions, six dfba− ligands and one hmt ligand. Each Cu2+ ion is coordinated in a square-pyramidal geometry with four oxygen atoms from four dfba− ligands and one nitrogen atom from a hmt ligand. The four oxygen atoms are located in the equatorial positions and the coordinated nitrogen atom is located at the axial position. The four dfba− ligands using four carboxylate groups link two Cu2+ ions with distances of 2.6164(6) Å for Cu1⋯Cu2, and 2.6659(8) Å for Cu3⋯Cu3i (Symmetry code: i − x + 1, − y, − z), respectively, to form [Cu2(COO)4] paddle wheel building blocks. Each hexamethylenetetramine ligands links the vertices of [Cu2(COO)4] paddlewheel units through three N atoms using μ3-bridging mode (Cu2—N1 = 2.196(3), Cu3—N4 = 2.207(3), and Cu1—N3ii = 2.211(3) Å, Symmetry code: iix + 1/2, − y + 1/2, z + 1/2). Therefore, a 2-D honeycomb structure is formed in the title complex.
