前驱团簇[Et4N]4[MS4Cu4I6](M=Mo(1a);W(1b))与双齿桥连配体1,2-双(4-吡啶基)乙烷(bpe)在苯胺溶液中反应,生成2个结构相似的一维[MS4Cu4]团簇基配位聚合物{[MS4Cu4(bpe)2(ani)2I2]·3.5ani}n(M=Mo(2),W(3);ani=苯胺)。通过元素分析、红外光谱和X-射线单晶衍射对2和3进行了表征。晶体结构分析表明前驱团簇1a和1b中五核马鞍形[MS4Cu4]簇核分别在2和3中得以保留,2个桥连配体bpe连接相邻的簇核,在[111]方向延伸形成一维“Z”字形链结构。
The precursor cluster [Et4N] 4 [MS4Cu4I6] (M = Mo (Ia); W (Ib)) and the bidentate ligand 1,2-bis (4-pyridyl) ethane (bpe) (M = Mo (2), W (3); 2) two kinds of structurally similar one-dimensional [MS4Cu4] ani = aniline). 2 and 3 were characterized by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction. The crystal structure analysis shows that the five-core saddle [MS4Cu4] cluster nuclei in the precursor clusters 1a and 1b are retained in 2 and 3, respectively. Two bridged ligands bpe are connected to the adjacent cluster nuclei and extend in the [111] direction One-dimensional “Z ” glyph chain structure.
