A new copper (Ⅱ) complex {[Cu2 (Phen) 4 (NO3)] [Cu (Ⅱ) was synthesized from 2-benzoylbenzoic acid (HL) and 1,10-phenanthroline (Phen) 2 (L)] 2 (L) 2 (NO3) 3} 2H2O (1). The crystal of this compound belongs to the triclinic system with the space group P1, with unit cell parameters of a = 1.138 57 (5) nm, b = 1.193 49 (7) nm, c = 2.615 31 ), Β = 82.753 (2) °, γ = 74.537 0 (10) °, V = 3.3968 (3) nm3, Dc = 1.408 g · cm -3, Z = 1 and μ (Mo Kα) = 0.700 mm- 1, F (000) = 1 480, final deviation factor R1 = 0.057 1, wR2 = 0.133 4. In the title complex molecule, there are two mononuclear cations [Cu (Phen) 2 (L)] + and one dinuclear cation [Cu2 (Phen) 4 (NO3)] 3+ The median is five. The electrochemical, fluorescence and magnetic properties of the title complex were determined. The results show that during the cyclic voltammetry, the electron transfer of the complex is quasi-reversible and the corresponding electrode reaction is Cu (Ⅱ) / Cu (Ⅰ). When the excitation wavelength is 488 nm, the complex is near 494 nm Strong fluorescence emission peak; at 300 ~ 52 K, the complex has diamagnetism.
