| 摘要: 合成了3个巢式磷碳硼烷镍配合物[NiCl(Py){7,8-(PPh2)2-7,8-C2B9H10}]·CH2Cl2(1)、[Ni{7,8-(PPh2)2-7,8-C2B9H10}2](2)、[Ni{7,8-(OPPh2)-7,8-C2B9 H10}{7,8-(PPh2)-7,8-C2B9H10}](3), 并通过元素分析、红外光谱、核磁共振谱以及单晶衍射等手段对其进行了表征。单晶结构分析表明, 镍离子的配位环境在这3个配合物中都是稍微扭曲的平面方形, 其中2个配位位置由磷碳硼烷配体的两个磷原子占据, 另外2个配位位置分别由氯离子、吡啶氮原子或者氧化的磷碳硼烷配体的氧原子占据。借助于分子间的C-H…Cl氢键或者C-H.H-B双氢键作用, 3个配合物都可以形成一维超分子结构。 | |

| Abstract: Three nickel carborane disphosphine complexes [NiCl(Py){7, 8-(PPh2)2-7,8-C2B9H10}]CH2Cl2(1), [Ni{7, 8-(PPh2)2-7, 8-C2B9H10}2](2) and [Ni{7, 8-(OPPh2)-7, 8-C2B9H10}{7, 8-(PPh2)-7, 8-C2B9H10}](3) have been synthesized and characterized by elemental analysis, FTIR, 1H and 13C NMR spectroscopy and X-ray structure determination. Single crystal analysis shows that the coordination environment of the Ni atom is a slightly distorted square-planar in the complexes 1~3, in which the four positions are occupied by two P atoms, one Cl atom and one N atom of pyridine in 1, four P atoms in 2 and two P atoms and two O atoms in 3, respectively. One dimensional chain structure can be formed depending on C-H…Cl or dihydrogen bonding interactions in these three complexes. CCDC: 749848, 1; 749846, 2; 799937, 3. | |
