Crystal structure of fac-tricarbonyl(cyclohexyl isocyanide-κC)(quinoline-2-carboxylato-κ2N,O)rhenium(I)

Abstract

In the title compound, [Re(C10H6NO2)(C7H11N)(CO)3], the ReI 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 octahedral. 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 interactions. Weak C—H...O hydrogen-bonding interactions 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.
