Embodiment 1

[0029] 1. Synthesis of single crystal of L-phenylalanine Schiff Base metal copper complex:

[0030] (1) 2-acetylpyridine-condensed L-phenylalanine Schiff Base ligand (C 16 h 16 o 2 N 2 ) of synthesis (the equation of synthesis reaction is as figure 1 shown): add 1 mmol (0.3304 g) of L-phenylalanine, 1 mmol (0.112 g) of potassium hydroxide and 15 mL of methanol in a dry 250 mL round bottom flask, and stir magnetically (1000 r) at room temperature until the solution changed from a suspension to a colorless clear solution. With the condenser installed, slowly add 0.23 mL (0.242 g) of 2-acetylpyridine dropwise to the colorless clear solution. The temperature of the water bath was raised to 50 °C, and the magnetic stirring (1000 r) was condensed and refluxed for 6 hours to obtain the ligand as a bright yellow transparent solution, which was cooled to room temperature.

Abstract

The invention discloses L-phenylalanine schiff-base metal copper complex monocrystalline and a preparation method thereof. A molecular formula of the complex monocrystalline is C32H30 Cl2Cu2N4O4, a space group is P21 / c, the cell parameter alpha is 12.4595(8) angstrom, b is 8.8566(6) angstrom, c is 14.5085(9) angstrom, alpha is 90 DEG, beta is 101.982(2) DEG C, gamma is 90 DEG, the crystal cell volume V is 1566.11(18) A<3>, and F(000) is 748. The method comprises the following steps: L-phenylalanine and 2-acetylpyridine are subjected to 2-acetylpyridine L-phenylalanine schiff-base ligand, and the ligand and bivalent copper salt are used for preparing the L-phenylalanine schiff-base metal copper complex monocrystalline by a one-step solvothermal method. According to the invention, the solvothermal method is employed for reactive synthesis of the ligand and the divalent metal copper ion copper ions to obtain the L-phenylalanine schiff-base metal copper complex under condition that high temperature for schiff base decomposition and high pressure due to boiling of methanol are not generated, the blue monocrystalline with good crystal form is obtained; the synthesis technology is simple, the prepared complex has a clear structure, the metal complex has amino acid synthesized schiff base ligand, so that the metal complex has latent important application prospect under antineoplastic aspect.
