The nickel(II) and copper(II) complexes of 2-substituted-4,4,4-trifluoro-1-(2-thienyl)butane-1,3-dione (R-TTAH) and their 2,2′ -bipyridine and 1,10-phenanthroline adducts have been prepared and characterized by microanalysis, conductance, magnetic and spectral measurements. The conductance data in nitromethane indicate that the compounds are non-electrolytes except for [Cu(Phen)2TTA](TTA) and [Ni(Phen)3](TTA)2
2-取代的4,4,4-三氟-1-(2-噻吩基)丁烷-1,3-二酮(R-TTAH)及其2,2'-的镍(II)和铜(II)配合物-已经制备了联吡啶和1,10-菲咯啉加合物,并通过微分析,电导,磁和光谱测量对其进行了表征。硝基甲烷中的电导数据表明,除[Cu(Phen)2 TTA](TTA)和[Ni(Phen)3 ](TTA)2分别为1:1和1:2电解质外,这些化合物均为非电解质。 。室温磁矩表明它们是磁性稀释的化合物,而配体的电子光谱(固体和溶液)带在螯合时发生移动。 红外光谱显示出羰基频率的不同位移,以及镍(II)离子通过4,4,4-三氟-1-(2-噻吩基)丁烷的四个氧原子配位而形成的六坐标八面体几何形状-1,3-二酮(TTAH)和联吡啶的两个氮原子被确定用于(2,2'-联吡啶)双4,4,4-三氟-1-(2-噻吩基)丁烷-1,3-用X射线晶体学分析二氧化镍。
