β-二酮及其衍生物的配合物作为分离试剂、发光材料及化学位移试剂已日益引起人们的重视。近年来,人们还开辟了4,4,4-三氟-1-(2-噻吩基)-1,3-丁二酮(HTTA)的一些稀土配合物的结构和红外光谱的研究。为了对这类化合物的特殊功能及结构特点进行更广泛的研究,本文报道以二甲亚砜为轴向加合的HTTA过渡金属铜(Ⅱ)配合物的晶体结构。实验晶体的制备将Cu(OAc)_2·2H_2O和HTTA溶于乙醇中,混合后析出绿色沉淀。沉淀用体积比H_3O:C_2H_5OH=2∶1的混合溶剂重结晶,所得的微晶进行元素分析,结果与Cu(TTA)_2
β-diketone and its derivatives as separation reagents, luminescent materials and chemical shift reagents have attracted more and more attention. In recent years, people have also opened up 4,4,4-trifluoro-1- (2-thienyl) -1,3-butanedione (HTTA) some rare earth complexes of the structure and infrared spectroscopy. In order to further investigate the special functional and structural characteristics of these compounds, the crystal structure of HTTA transition metal copper (II) complexed with dimethyl sulfoxide is reported. Preparation of experimental crystals Cu (OAc) 2 · 2H 2 O and HTTA were dissolved in ethanol and mixed to precipitate a green precipitate. The precipitate was recrystallized with a mixed solvent of volume ratio H_3O: C_2H_5OH = 2: 1, and the obtained crystallites were subjected to elemental analysis. As a result, the precipitates were separated from Cu (TTA) _2
