Syntheses, crystal structures and density functional theory investigations of copper(ii) complexes bearing tridentate Schiff base ligands derived from 8-aminoquinoline

Abstract

Three copper(II) Schiff base complexes have been synthesized and characterized. The theoretical study, carried out using density functional theory calculations, is devoted to the analysis of the interesting supramolecular assemblies in the solid state of the structures, paying special attention to lp−π and π−π interactions.

Modulation in π⋯π, cation⋯π and C–H⋯H–C interactions varying the counter anions in square planar nickel(II) Schiff base complexes: A combined experimental and theoretical study

“…On the other hand, the importance of the anion•••π interactions has been explored in gas phase, in solution, and in the solid state, and has also been analyzed by means of theoretical and experimental investigations [32][33][34][35][36][37][38][39][40][41]. Many researchers are synthesizing several supra-molecular architectures and analyzing the energy of these associations to understand the nature of cooperative non-covalent interactions in them [42][43][44][45][46][47][48][49][50][51].…”

Homoleptic CoII, NiII, CuII, and ZnII Complexes Based on 8‐Hydroxylquinoline Schiff Base Derivative: a Combined Synthetic, Spectral, Structural, and Magnetic Study

“…In the tridentate ONX‐type family, albeit much less well developed, quinoline salicylaldimine based ligands, have been investigated for their versatility towards various transition metal with interesting structural, biological, optical, magnetic and catalytic properties . The tridentate quinoline Schiff bases act as planar monoanionic ligands incorporating the pyridine moiety and exhibiting an extended π‐system.…”

Carboxylate Coordination Assisted Aggregation for Quasi‐Tetrahedral and Partial‐Dicubane [Cu4] Coordination Clusters

“…Hence, formate anion can offer different bridging modes in such aggregation process . Further interactions between individual molecular fragments bearing dangling ether‐alcohol arms can impart stability through hydrogen bonding [6a–6c] and van der Waals interactions– which is not observed in absence of such arms. Studies on these interactions are important in relation to their effect for the growth of new supramolecular structures .…”
