Structures of silver nitrate complexes with quinolines according to NMR data

详细

Silver(I) nitrate complexes [AgNO₃(L)₂], where L is quinoline or 2-, 4-, and 8-methylquinoline, are synthesized and studied by the multinuclear NMR (¹H, ¹³C, ¹⁵N) method in acetonitrile. The influence of steric and electronic factors of the organic ligand on the NMR spectral parameters is revealed. The fast chemical exchange of the free and coordinated ligands is observed at room temperature. The ¹⁵N NMR spectra are most informative. The formation of a complex with 8-methylquinoline is impeded because of steric hindrances.
