Two fac-Re(CO)₃ core based dinuclear complexes were obtained from Re₂(CO)₁₀, 1,4-phenylene-bis(2-(2′-hydroxyphenyl)benzimidazolyl) (H₂-L) and neutral N-donors (4-(amino)pyridine/4-(dimethylamino)pyridine). Both the complexes are characterized using various analytical and spectroscopic techniques. The molecular structure of 2 obtained from a SCXRD analysis shows that two anionic phenoxybenzimidazolyl motifs of L²⁻ are twisted, resulting in an acyclic dinuclear helical structure. Both the complexes display strong emission in the solution state at room temperature.

基于2-（2'-羟苯基）苯并咪唑基的双螯合配体和4-（氨基）吡啶/ 4-（二甲基氨基）吡啶的hen（I）络合物

两个FAC -重（CO）_3个，从重新获得的基于核心双核配合物₂（CO）₁₀，1,4-亚苯基双（2-（2'-羟基苯基）苯并咪唑基）（H ₂ -L）和中性N-供体（4-（氨基）吡啶/ 4-（二甲基氨基）吡啶）。两种配合物均使用各种分析和光谱技术进行表征。从SCXRD分析获得的2的分子结构表明，L ^2-的两个阴离子苯氧^基苯并咪唑基基序被扭曲，从而形成无环双核螺旋结构。两种络合物在室温下在溶液状态下均显示强发射。
