合成了一个新的4,6-二甲基-2-嘧啶硫乙酸与铜的双核簇合物[Cu2(dmpytaa)4(CH3OH)2]·3CH3OH(Hdmpytaa=4,6二甲基2嘧啶硫乙酸),通过X射线衍射、红外光谱、紫外光谱、热重分析对其进行了结构表征。该晶体属于三斜晶系,空间群P1-,晶胞参数:a=509(3),b=13.526(3),c=15.396(3),α=70.68(3)°,β=68.82(3)°,γ=88.73(3)°,V=2460.3(9)3,μ=1.100mm-1,Dc=1.453gcm3,F(000)=1120,R=0.0537,wR=0.1227(I>2σ(I)),6942个可观察衍射点。该双核分子中两个中心金属Cu原子均处于扭曲的八面体构型中心,并分别与来自四个不同羧酸配体上的羧基氧原子,一个溶剂甲醇分子中的氧原子,以及相邻的一个Cu原子配位。
A new dinuclear cluster [Cu2 (dmpytaa) 4 (CH3OH) 2] · 3CH3OH (Hdmpytaa = 4,6-dimethylpyrimidine sulfur Acetic acid), and its structure was characterized by X-ray diffraction, infrared spectrum, ultraviolet spectrum and thermogravimetry. The crystal belongs to the triclinic system with a space group P1- with unit cell parameters of a = 509 (3), b = 13.526 (3), c = 15.396 (3), a = 70.68 (I) 3) °, γ = 88.73 (3) ° V = 2460.3 (9) 3 μ = 1.100 mm-1 Dc = 1.453 gcm3 F (000) = 1120 R = 0.0537 wR = 0.1227 (I)), 6942 observable diffraction points. The two central metal Cu atoms in the binuclear molecule are in the center of the distorted octahedral configuration and react with carboxyl oxygen atoms from four different carboxylic acid ligands, oxygen atoms in one solvent methanol molecule, and adjacent A Cu atom coordination.
