| Two One-Dimensional [MS4Cu4]-Supported Coordination Polymers: Assembly and Crystal Structures of {[MS4Cu4(bpe)2(ani)2I2]·3.5ani}n (M=Mo, W; ani=aniline) | |
| 摘要: 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。 | |

| Abstract: Reactions of the preformed cluster precursors [Et4N]4[MS4Cu4I6] (M=Mo (1a); W (1b)) with a ditopic bridging ligand 1, 2-bis(4-pyridyl)ethane (bpe) in aniline solutions gave rise to two analogous one-dimensional cluster-supported coordination polymers {[MS4Cu4(bpe)2(ani)2I2]·3.5ani}n (M=Mo (2), W (3); ani=aniline). Both 2 and 3 are characterized by elemental analysis, IR spectra, and single crystal X-ray diffraction. X-ray analyses revealed that the pentanuclear saddle-shaped [MS4Cu4] cores in 1a and 1b are retained in 2 and 3. The adjacent [MS4Cu4] cores are interconnected by double bpe bridges to afford one-dimensional zigzag chains extending along the [111] direction. | |
