Supramolecular organization in crystals containing quinoline-2-carboxylates and 9,10-dihydro-9-oxo-10-acridineacetates

Abstract

Coordination compounds containing quinoline-2-carboxylate (quin-2-c) or 9,10-dihydro-9-oxo-10-acridineacetate ion (CMA) and ancillary ligands capable of hydrogen bond formation self assemble into 1D, 2D or 3D networks. The system of intermolecular hydrogen bonds that emerges depends mainly on the nature of the ancillary ligand. Aromatic–aromatic and C–H … π interactions are important forces for stabilizing crystal structures. Very strong stacking of aromatic heteropolycycles is found. An overview of complexes with quin-2-c and CMA is given and the organization of their crystal structures discussed.
