摘　　要：由[Cu(MeCN)2 (PPh3)2 ](BF4 )和 4′ 苯基 2,2′:6′,2″ 三联吡啶(4′ Phtpy)在室温下反应,合成了一个新颖的具有光致发光性能的五配位配合物[Cu(4′ Phtpy)(PPh3)2 ](BF4 ).对配合物进行了X射线衍射结构表征,并进行了红外光谱、紫外可见光谱、荧光光谱等光谱学分析.晶体属单斜晶系,空间群Pn,晶胞参数:a =1 0 80 7(6)nm,b =1 0 943 (6)nm,c=2 1610(12 )nm,α =90°,β =10 2 785(10 )°,γ =90°,V =2 492(2 )nm3,Z =2,Dc=1 3 5 4g·cm-3.配合物中,Cu(Ⅰ)与 4′ Phtpy的 3个N,2个PPh3的P配位呈变形三角双锥型结构,其轴向由Cu键合联吡啶的末端 2个N所组成,赤道平面由联吡啶的中心N原子和A luminescence five-coordinated copper(Ⅰ) complex of [Cu(4′-Phtpy)(PPh_3)_2](BF_4) has been prepared by the reaction of [Cu(MeCN)_2(PPh_3)_2](BF_4) 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 PPh_3.
