In the title compound, [Re(C10H6NO2)(C7H11N)(CO)3], the Re(I) atom is coordinated by three carbonyl ligands in a facial arrangement and by the N, O and C atoms from a chelating quinaldate anion and a monodentate isocyanide ligand, respectively. The resultant C4NO coordination sphere is distorted octa-hedral. A lengthening of the axial Re-CO bond trans to the isocyanide ligand is indicative of the trans effect. Individual complexes are stacked into rods parallel to [001] through displaced π-π inter-actions. Weak C-H⋯O hydrogen-bonding inter-actions between the rods lead to the formation of layers parallel to (010). These layers are stacked along [010] by C-H⋯H-C van der Waals contacts.
在标题化合物[Re(C₁₀H₆NO₂)(C₇H₁₁N)(CO)₃]中,Re(I)原子由三个呈面式排列的羰基配体配位,并且分别由螯合喹哪啶阴离子和单齿异腈配体中的N、O和C原子配位。由此形成的C₄NO配位球呈扭曲八面体形状。与异腈配体反位的轴向Re-CO键伸长表明了反位效应。单个配合物通过错位的π-π相互作用堆积成平行于[001]的棒状结构。棒状结构之间的弱C-H⋯O氢键相互作用导致形成平行于(010)的层。这些层通过C-H⋯H-C范德华接触沿[010]堆叠。
