采用间氯苯甲酸(m-CBA)、1,10-菲罗啉(phen)和醋酸铜合成一种新颖配合物Cu(phen)(m-CBA)2,并用红外光谱、紫外可见光谱、元素分析、X-射线单晶衍射对其进行表征。结果表明,该配合物为单斜晶系,空间群为C2/c,晶胞参数为a=2.9699(4)nm,b=1.15452(2)nm,c=1.5335(2)nm,β=111.118(2)°,V=4.9051(1)nm3,Z=8,F(000)=2328,R1=0.0728,wR2=0.2234[I>2σ(I)]。结果分析表明,中心铜原子和来自1个1,10-菲罗啉分子的2个氮原子、2个间氯苯甲酸分子的2个氧原子进行配位,形成一个变形平面四边形的配位模式。该配合物中铜原子之间存在顺磁相互作用。
A new complex, Cu (phen) (m-CBA) 2, was synthesized by using m-CBA, 1,10-phenanthroline and copper acetate and characterized by IR, UV- Analysis, X-ray single crystal diffraction characterization. The results show that the complex is monoclinic with a space group of C2 / c with unit cell parameters of a = 2.9699 (4) nm, b = 1.15452 (2) nm, c = 1.5335 (2) °, V = 4.9051 (1) nm3, Z = 8, F (000) = 2328, R1 = 0.0728, wR2 = 0.2234 [I> 2σ (I)]. The results show that the central copper atoms and two nitrogen atoms from one 1,10-phenanthroline molecule and two oxygen atoms of two m-chlorobenzoic acid molecules coordinate to form a complex quadrangular tetragonal coordination mode . There is paramagnetic interaction between the copper atoms in the complex.
