Synthesis,crystal structure and quantum chemical calculation of a Cu(Ⅱ) coordination polymer
【摘要】 在甲醇水混合溶剂中,以α-吡啶甲酸为配体与氢氧化铜合成了标题配合物[Cu(C6H4NO2)2]n·2nH2O。配合物(C12H12CuN2O6,分子量为343.79),晶体属三斜晶系,空间群P1,晶胞参数:a=0.51239(9)nm,b=0.76278(13)nm,c=0.92161(16)nm,α=74.921(3),β=84.404(3)°,γ=413(2),V=329.62(10)nm3,Dc=1.732 cm3,Z=1,F(000)=175,μ=1.69mm-1。最终偏离因子R1=0.0265,wR2=0.0711。晶体结构表明:铜原子与2个α-吡啶甲酸4个氧原子,2个氮原子配位,形成六配位的变形四面体结构。本文对该配合物进行了量子化学计算。
【Abstract】 The title complex has been synthesized with pyridine carboxylic acid and the copper hydroxide in the solvent mixture of water and methanol.It crystallizes(C12H12CuN2O6,Mr=343.79)in Triclinic space group P-1with:a=0.51239(9)nm,6=0.76278(13)nm,c = 0.92161(16) did,α=74.921(3),β=84.404(3)°,γ=71.413(2);V=329.62(10)nm3,Dc=1.732 cm3,Z=1,F(000)=175,μ=1.69 mm-1,R1= 0.0265,wR2 =0.0711. The crystal structure shows that the copper atom is coordinated with four oxygen atoms and nitrogen atoms from two pyridine carboxylic acid molecules,forming a distorted octahedral coordination geometry.The stability,some frontier molecular orbital energies and composition characteristics of some frontier molecular orbital of the complex have been investigated.
