X-ray diffraction study of tetranuclear organobismuth complexes Bi4(O)2(O2CC6H2F3-3,4,5)8 · 2η6-C6H6 and Bi4(O)2(O2CC6H2F3-3,4,5)8 · 2(C6H4Me2-1,4) revealed four Bi atoms connected through the bridging carboxylate ligands and the O atoms. The coordination sphere of the terminal Bi atoms includes the chelate carboxylate ligand and the η6-arene molecule. The bridging O atoms are tricoordinated, the distances between the terminal Bi atom and the center of benzene molecule (1,4-dimethylbenzene) are 3.024 Å(3.131 Å).
对四核有机铋配合物 Bi4(O)2(O2CC6H2F3-3,4,5)8 - 2η6-C6H6 和 Bi4(O)2(O2CC6H2F3-3,4,5)8 - 2(C6H4Me2-1,4)的 X 射线衍射研究表明,四个铋原子通过桥接羧酸配体和 O 原子连接在一起。末端 Bi 原子的配位圈包括螯合羧酸配体和 η6- 烯分子。桥接的 O 原子为三配位,末端 Bi 原子与苯分子(1,4-二甲基苯)中心的距离为 3.024 Å(3.131 Å)。
