【Abstract】 A luminescence five-coordinated copper（Ⅰ） complex of [Cu（4′-Phtpy）（PPh₃）₂]（BF₄） has been prepared by the reaction of [Cu（MeCN）₂（PPh₃）₂]（BF₄） and 4′-Phtpy （4′-Phtpy = 4′-phenyl-2,2′:6′, 2″-terpyridine） at room temperature. The complex was characterized with single crystal X-ray diffraction analysis, as well as IR, UV-vis absorption and luminescence spectrometry. X-ray structural data show that the crystal belongs to monoclinic system, and Pn space group with cell parameters a=1 0807（6） nm, b=1 0943（6） nm, c=2 1610（12） nm, α=90°, β=102 785（10）°, γ=90°, V=2 492（2） nm 3, Z=2, D_c=1 354 g·cm -3. The copper（Ⅰ） ion in the complex has a distorted trigonal bipyramidal geometry, with the metal atom coordinated by two nitrogen atoms from the distal terpyridine pyridyl rings in axial sites. The equatorial plane is defined by the binding of nitrogen atom from the central pyridyl and two phosphorus atoms from PPh₃.更多还原
