Heteroleptic copper(I) complexes prepared from phenanthroline and bis-phosphine ligands

Preparation of [Cu(NN)(PP)]+ derivatives has been systematically investigated starting from two libraries of phenanthroline (NN) derivatives and bis-phosphine (PP) ligands, namely, (A) 1,10-phenanthroline (phen), neocuproine (2,9-dimethyl-1,10-phenanthroline, dmp), bathophenanthroline (4,7-diphenyl-1,10-phenanthroline, Bphen), 2,9-diphenethyl-1,10-phenanthroline (dpep), and 2,9-diphenyl-1,10-phenanthroline (dpp); (B) bis(diphenylphosphino) methane (dppm), 1,2-bis(diphenylphosphino)ethane (dppe), 1,3- bis(diphenylphosphino)propane (dppp), 1,2-bis(diphenylphosphino)benzene (dppb), 1,1′-bis(diphenylphosphino)ferrocene (dppFc), and bis[(2- diphenylphosphino)phenyl] ether (POP). Whatever the bis-phosphine ligand, stable heteroleptic [Cu(NN)(PP)]+ complexes are obtained from the 2,9-unsubstituted-1,10-phenanthroline ligands (phen and Bphen). By contrast, heteroleptic complexes obtained from dmp and dpep are stable in the solid state, but a dynamic ligand exchange reaction is systematically observed in solution, and the homoleptic/heteroleptic ratio is highly dependent on the bis-phosphine ligand. Detailed analysis revealed that the dynamic equilibrium resulting from ligand exchange reactions is mainly influenced by the relative thermodynamic stability of the different possible complexes. Finally, in the case of dpp, only homoleptic complexes were obtained whatever the bis-phosphine ligand. Obviously, steric effects resulting from the presence of the bulky phenyl rings on the dpp ligand destabilize the heteroleptic [Cu(NN)(PP)]+ complexes. In addition to the remarkable thermodynamic stability of [Cu(dpp)2]BF4, this negative steric effect drives the dynamic complexation scenario toward almost exclusive formation of homoleptic [Cu(NN)2]+ and [Cu(PP)2]+ complexes. This work provides the definitive rationalization of the stability of [Cu(NN)(PP)]+ complexes, marking the way for future developments in this field.

Supramolecular encapsulation of anions in a copper(I) complex

Mixed ligand copper(I) complexes of 1,10-phenanthroline (phen) and 1,2-bis(diphenyl)phosphinoethane (dppe) have been prepared with different counter ions [ClO4- (1), BF4- (2), SO42- (3), NO3- (4)]. Based on the 1H and 31P NMR spectra of these complexes, it is seen that the solution equilibria of the sulfate complex is different from the rest and involves ligand dissociation. Competition experiments show that the nitrate ion is preferred by the cation in solution. Complex 4 has 1H NMR features that are different from those observed in complexes 1 and 2. A Cambridge Structural Database study has been taken up to show the uniqueness of phenanthroline in interacting with anions, especially nitrate ions through a preferential (phen)C2-O(nitrate) interaction.
