[0034] Cu(BF 4 ) 2 and 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) in a molar ratio of 1: 1;

[0035] tatrz (0.0624 g, 0.2 mmol) and Cu(BF 4 ) 2 (0.0691 g, 0.2 mmol) in H 2 O (6 mL) and CH 3 CN (4 mL) was stirred in a mixed solvent at room temperature for half an hour and then filtered, and the filtrate was volatilized at room temperature to form yellow rod-shaped crystals analyzed by X-ray single crystal diffraction. Yield: 35% (calculated based on tatrz). Elemental analysis (C 36 h 28 B 2 CuF 8 N 12 o 2 ) Theoretical value (%): C, 48.16; H, 3.14; N, 18.72. Found: C, 48.15; H, 3.16; N, 18.69.

Embodiment 3

[0037] The crystal structure was determined using an APEX II CCD single crystal diffractometer, using graphite monochromatized Mokα rays (λ = 0.71073 ?) as the incident radiation, and ω -2 θ Diffraction points are collected by scanning, and the unit cell parameters are obtained by least square method correction. The crystal structure is solved by software from the difference Fourier electron density map, and corrected by Lorentz and polarization effects. All H atoms were synthesized by difference Fourier transform and determined by ideal position calculation. The detailed crystal determination data are shown in Table 1. Structural primitives see figure 1 , the three-dimensional structure of the complex see figure 2 .
