) (2) (where L
1
is 3-(4-(1H-benzo[d]imidazol-1-yl)-4-methoxy phenyl)-1-phenylprop-2-en-1-one; tta is 2-thenoyltrifluoroacetonate), are reported. Their structures have been characterized by infrared spectroscopy, elemental analyses and single-crystal X-ray diffraction. The copper(II) ion of 1 is in a distorted octahedral environment, while that of 2 is in a distorted square-pyramidal environment. In both cases, the donor atoms are provided by oxygen atoms of the tta ligands and nitrogen atoms of the L

ligands.
摘要 报道了两种新的铜(II)配合物的合成,它们与苯并咪唑类配体配位,分别为Cu(tta)2(L1)2 (1)和Cu(tta)2(L1) (2) (其中L1为3-(4-(1H-苯并[d]咪唑-1-基)-4-甲氧基苯基)-1-苯基丙烯酮; tta为2-硫代苯并三氟乙酮酸酯)。它们的结构通过红外光谱、元素分析和单晶X射线衍射进行了表征。1的铜(II)离子处于扭曲的八面体环境中,而2的铜(II)离子处于扭曲的方锥环境中。在两种情况下,供体原子由tta配体的氧原子和L1配体的氮原子提供。
