Synthesis, crystal structure, and luminescent properties of silver complexes with 2-methylquinoline

The complexes [AgL 2 (NO 3 )] ( I ) and [AgL 2 (CH 3 SO 3 )] · H 2 O ( II ) (L is 2-methylquinoline, C 10 H 9 N) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Crystals of I are monoclinic, space group P 2 1 / n , a = 9.296(1) Å, b = 13.495(1) Å, c = 14.931...

Description
Summary:The complexes [AgL 2 (NO 3 )] ( I ) and [AgL 2 (CH 3 SO 3 )] · H 2 O ( II ) (L is 2-methylquinoline, C 10 H 9 N) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Crystals of I are monoclinic, space group P 2 1 / n , a = 9.296(1) Å, b = 13.495(1) Å, c = 14.931(1) Å, β = 95.06(1)°, V = 1865.8(3) Å 3 , ρ calc = 1.624 g/cm 3 , Z = 4. Crystals of II are monoclinic, space group P 2 1 / n , a = 13.147(1) Å, b = 11.767(1) Å, c = 13.814(1) Å, β = 96.06(1)°, V = 2124.3(3) Å 3 , ρ calc = 1.599 g/cm 3 , Z = 4. Compounds I and II are composed of discrete complexes of similar structure but with different orientation of the methyl groups of ligand L ( trans and cis arrangement, respectively). Both anions, NO 3 - and CH 3 SO 3 - function as a chelating weakly bound ligand for the Ag + ion. The presence of water molecules in II is favorable for the formation of dimeric supramolecular moieties between the centrosymmetrically arranged Ag + complexes with 2-methylquinoline. The luminescence spectra of solid complexes I and II showed a bathochromic shift as compared to the spectrum of L in acetonitrile. Complexes I and II have been characterized by 1 H and 13 C{H} NMR spectra in CD 3 CN.
