Source of material
The title complex was synthesized by hydrothermal synthesis. CuCl2 (0.017 g, 0.1 mmol), 1,10-phenanthroline (0.02 g, 0.1 mmol), 6-hydroxy-2-phenylpyrimidine-4-carboxylic acid C11H8CN2O3 (0.0432 g, 0.2 mmol), and H2O (6 mL) were stirred at room temperature for 1 h and then put in a 20 mL high pressure reaction vessel. The autoclave was heated in an oven at 140° for 3 days and then cooled to room temperature to obtain blue flakes of the complex based on copper chloride. Then the complex was washed several times with deionized water and filtered to give crystals. Yields: 47.65%. 6-hydroxy-2-phenyl-pyrimidine-4-carboxylic acid was prepared by reference [5]. 1H NMR (600 MHz, DMSO) δ: 6.87 (s, DiazineH, 1H), 7.54–7.56 (m, PhH, 2H), 7.60 (d, J = 6 Hz, PhH, 1H), 8.17–8.18 (d, J = 6 Hz, PhH, 1H) ppm.
Experimental details
The structure was determined by the intrinsic phasing routines in the SHELXT program [2] and refined in SHELXL [3] using Olex 2 [4]. All of the hydrogen atoms were placed in the calculated positions.
Comment
Metal complex have the advantages of biological activity, excellent porosity, high loading capacity, etc. and play an important role in biomedical applications. It could be used to effectively load drugs and is beneficial to package various compounds and therapeutic drugs [6], [7]. The complexes formed with Cu2+ have thousands of applications; for example as nucleic acid cleavage enzymes because of their cleavage activity to DNA, and some complexes have certain anticancer activities [8], [9]. As a new type of ligand, 6-oxo-2-phenyl-1,6-dihydropyrimidine-4-carboxylate coordinate with Cu2+ to form the title complex. A TG curve was obtained. From the thermo gravimetric curve it could be found that there were two parts in weight loss, indicating that each organic ligand in the complex is removed seperately respectively. When the temperature was between 286 and 463°C, there was rapid weight loss, which meant the collapse of the whole system: weight loss 61.83%. Bond lenghts and angles are all in the expected ranges.
