1 Source of materials

The starting material, (4-methoxyphenyl)picolinamide (L), was prepared as follows: 2.46 g (20.0 mmol) of pyridine-2-carboxylic acid solution was prepared by adding it to 12.0 mL of pyridine. To this solution, 2.20 mL (20.0 mmol) of 4-methoxyaniline were added, and the mixture was heated with continuous stirring for 30.0 min. Subsequently, 5.28 mL (20.0 mmol) of triphenylphosphite were introduced into the resulting solution, and the mixture was stirred at 110 °C for 4 h. The cold reaction mixture was washed with 100.0 mL of distilled water, and the resulting white paste was dissolved into 50.0 mL of dichloromethane. It was then extracted with 100.0 mL of 1:1 (v/v) aqueous hydrochloric acid. The aqueous extract was neutralized using solid sodium bicarbonate. The resulting white solid was filtered, thoroughly washed with distilled water, and subsequently crystallized from aqueous methanol, yielding a colorless crystalline solid. The overall yield of the process was 89.0 %. The copper complex was obtained by the following procedures: A 250.0 mL round bottom flask was charged with 693.0 mg (3.04 × 10−3 mmol) of L and added 20.0 mL of absolute ethanol and continued to stirring at room temperature until all the ligands dissolved. Then, 6.0 mL of 28 % NH3 solution and 259.2 mg (1.52 × 10−3 mmol) of CuCl2 · 2H2O were added to the solution and refluxed the rection mixture for 19 h at 80 °C. The final green solid product was separated with filtration and washed with cold ethanol for removing unreacted metal salt and ligand. Finally, the desired product was isolated as green crystalline material by slow evaporation from hot ethanol and diethyl ether mixture. Yield 85.0 %.

2 Experimental details

The chemicals were purchased from Aldrich (Germany), Fluka (Switzerland), and were used without further purification, unless otherwise stated. Single crystals were obtained through crystallization of the pure compound from slow evaporation of EtOH/Et2O. The collected frames were integrated with the Bruker SAINT software package using a narrow-frame algorithm. Data correction were performed for absorption effects using the multi-scan method (SADABS). The structure was solved and refined using the Bruker SHELXTL [3] software package. Using Olex2 [2], the structure was further refined with the ShelXL [4] refinement package using least squares minimization. All H atoms bonded to C atoms were refined as riding, with C–H distances of 0.93 Å (for aromatic ring).

3 Comment

Picolinamide derivatives are known to act as bidentate ligands [5]. The interest in these ligands arises not only from their anticancer activity but also from their ability to form linkage isomers that depend on the acidity of the medium [6]. Furthermore, these compounds play a key role task in the advancement of coordination chemistry that is related to catalysis, magnetism, and molecular design [7]. Copper, one of essential trace elements in biological systems, can be used as a substitute in cisplatin complexes [8]. In view of the interest in the activity spectrum and profile of picolinamide derivatives, herein we present the title structure of picolinamide copper complex.

The asymmetric unit shows one complex. The coordination sphere of copper(II) consists of two picolinamide ligands. The average Cu–N bond is 1.978 Å (Cu–N1 = 2.000(2) Å, Cu–N2 = 1.999(2) Å, Cu–N4 = 1.958(2) Å, and Cu–N5 = 1.953(2) Å) [9]. The copper(II) is distorted from square planar geometry with an average chelate angle equal to 83.5° (N4–Cu–N2 and N5–Cu–N1) and the other cis nitrogen (N4–Cu–N1 and N5–Cu–N2) have an average angle equal to 101.8°. Trans-nitrogens angles (N2–Cu–N1 and N5–Cu–N4) show 147.2° and 161.3°, respectively. Furthermore, the two ligands that are attached to the copper(II) center are not coplanar. The angle between the mean plane that passes through (N1–Cu–N5–C6–C5) and (N2–Cu–N4–C12–C13) is equal 40.7°. The structure of crystal is being stabilized by the presence of shortest hydrogen bonds between the carbonyl-oxygen atoms O5 (−x, −y, −z) and H15 (−x, 1 − y, −z) with distances equal to 2.382 Å. A weaker hydrogen bond interaction is formed between H17 (−1 + x, 1 + y, +z) and the carbonyl-oxygen atom O5 (−x, −y, −z) with distance equal to 2.464 Å.
