摘要 以5-氟水杨酸和邻菲罗啉为定向配体,与乙酸铜反应经溶剂热法合成了一个新的单核铜(Ⅱ)配合物[Cu(fiac)(1,10-phen)]·H2O(1)(Hfiac=5-氟水杨酸,1,10-phen=邻菲罗啉),并对结构进行了单晶X-射线衍射表征、元素分析和红外光谱分析。配合物1属于三斜晶系,Pī空间群,晶胞参数a=1.11401(6)nm,b=1.20947(10)nm,c=1.40478(17)nm;α=7.2680(11)°,β=75.090(9)°,γ=76.300(6)°,V=1719.6(3),Z=2,Dc=2.425g·cm-3,R1=0.0411,wR2=0.1108,S=1.110。配合物1中的Cu(Ⅱ)离子分别与来自二齿配体Hfiac上的两个O原子和来自邻菲罗啉配体上的两个N原子配位,形成平面构型。通过对配合物1的荧光性能研究,结果表明其具有一定的荧光特性。 A new copper complex [Cu(fiac)(1,10-phen)] · H2O (1) (Hfiac = 5-fluorine salicylic acid, 1, 10-phen : 1,10-phenanthroline) was synthesized by solvothermal method from 5-fluorine salicylic acid, 1, 10-phenanthroline and Cu(AC)2 · H2O. The structure was characterized by IR, elemental analysis and X- ray single-crystal diffraction. Complex 1 belongs to the triclinic system, space group Pi, with a = 1. 11401 (6) nm, b = 1. 20947 (10) nm, c : 1. 40478 (17) nm; α = 72. 680 (11) °, β = 75. 090 (9) °, γ = 76.300 (6)°, V = 1719.6 (3), Z = 2, Dc = 2.425 g·cm-3, RI= 0.0411, wRz= 0.1108, S = 1. 110. The Cu( Ⅱ ) ion is four coordinated with two O atoms from 5-fluorine salicylic acid ligand and two N atoms from 1,10-phenanthroline ligand to form a plane geometry. The results of fluorescence tests show that complex 1 has fluorescence properties.
