Neutral heteroleptic acyclic complex, fac−[Re(CO)₃(OQN)(pybimz)] (1), possessing free benzimidazole motif remotely is reported. The complex was obtained from 8-hydroxyquinoline (HOQN), 2-(4′-pyridyl)benzimidazole (pybimz), and Re₂(CO)₁₀. The structure of 1 was confirmed using single crystal X-ray diffraction (SCXRD) analysis. The crystal structure of 1 is stabilized by various types of intermolecular non-covalent interactions (π_(OQN) ⋅⋅⋅π_(OQN), NH^CH_(pybimz)⋅⋅⋅O_(OQN)−Re, and C−H_(pybimz)⋅⋅⋅O≡C−Re). The extended H-bonding contacts between the molecules (C−H_(pybimz)⋅⋅⋅O≡C−Re) in the crystal structure result in the cavity containing polymeric network structure in which toluene molecules reside. The solvent toluene molecules occupy ∼35% of the unit cell volume of the crystal. The absorption properties of the complex was studied both experimentally and theoretically.

据报道，中性杂配无环复合物fac -[Re(CO) ₃ (OQN)(pybimz)] ( 1 )，远程拥有游离苯并咪唑基序。该复合物由 8-羟基喹啉 (HOQN)、2-(4'-吡啶基)苯并咪唑 (pybimz) 和 Re ₂ (CO) _{10 获得}。使用单晶X射线衍射（SCXRD）分析证实了1的结构。的晶体结构1是由各种类型的分子间非共价相互作用的（π稳定_（OQN） ⋅⋅⋅π _（OQN），NH 2 CH _{（pybim Ž ）} ⋅⋅⋅O _（OQN） -Re和CH _(pybimz)⋅⋅⋅O≡C−Re）。晶体结构中分子 (C−H _(pybimz) ⋅⋅⋅O≡C−Re)之间扩展的氢键接触导致含有甲苯分子驻留的聚合物网络结构的空腔。溶剂甲苯分子占晶体晶胞体积的约 35%。通过实验和理论研究了配合物的吸收特性。
