1 Source of materials

The title compound was synthesized by dissolving NaOH (0.040 g, 1.0 mmol), 6-phenylpyridine-2-carboxylic acid (0.9960 g, 0.5 mmol), 2,2′-bipyridine-6-carboxylic acid (0.100 g, 0.5 mmol) in 5 mL aqueous solution with stirring. Then 15 mL of a 95% ethanol solution containing Cu(O2CMe)2.H2O (0.0999 g, 0.50 mmol) was added. The mixture was stirred at 70 °C for 4.5 h. The filtrate was evaporated at room temperature, and gave a colourless block crystal of the title complex in 15 days. Yield 62%. Anal. Calcd. for C23H17N3O5Cu: C, 57.63; H, 3.55; N, 8.77. Found: C, 57.38; H, 3.82; N, 8.39.

2 Experimental details

The hydrogen atoms were positioned geometrically (C–H = 0.93 Å and O–H = 0.85 Å). Their U iso values were set to 1.2U eq or 1.5U eq of the parent atoms.

3 Comment

Transition metal complexes constructed from carboxylic acid-containing group ligands are an important class of compounds with interesting structures and functional properties. So the study of these compounds has been one of the hot research topics. They can show structural diversity [5], and promising potential applications in many aspects of luminescence property [6], anticancer activity [7], catalytic activities [8, 9], and antibacterial agent [10]. In recent years, we have also synthesized and structurally characterized several transition metal complexes with ligands containing carboxylic acid group [11, 12]. However, no literature reports on the synthesis and structure of copper complex with 2,2′-bipyridine-6-carboxylic acid and 6-phenylpyridine-2-carboxylic acid ligands.

The molecular structure of the title complex is shown in the figure. It consists of one Cu2+ ion, one 2,2′-bipyridine-6-carboxylato ligand, one 6-phenylpyridine-2-carboxylate ligand and one uncoordinated water molecules. The Cu(II) is ion coordinated with two nitrogen atoms (N1, N2) from one 2,2′-bipyridine-6-carboxylato ligand, one nitrogen atom (N3) from one 6-phenylpyridine-2-carboxylate ligand, one oxygen atom (O2) from one 2,2′-bipyridine-6-carboxylato ligand, and one oxygen atom (O3) from one 6-phenylpyridine-2-carboxylate ligand. The coordination environment around Cu(II) ion is a distorted bipyramid with N1, N2, O2 and O3 at the position. The 2,2′-bipyridine-6-carboxylato ligand adopts tridentate coordination mode and the 6-phenylpyridine-2-carboxylate ligand adopts bidentate coordination mode. The dihedral angles of two pyridine rings (N1–C14–C15–C16–C17–C18) and (N2–C19–C20–C21–C22–C23) is 2.33 Å, showing that the 2,2′-bipyridine-6-carboxylato ligand is coplanar. However, the dihedral angle of pyridine ring (N3–C2–C3–C4–C5–C6) and benzene ring (C7–C8–C9–C10–C11–C12) is 37.83 Å°, showing that the 6-phenylpyridine-2-carboxylate ligand is not coplanar. The Cu–N and Cu–O distances are 1.9163(12)–2.2710(12) Å and 2.0018(11)–1.9176(11) Å. The hydrogen bonds (O–H···O) between the uncoordinated water molecules and O atoms of 2,2′-bipyridine-6-carboxylato and 6-phenylpyridine-2-carboxylate ligands create a 1D structure.
