X-ray Crystal Structures of Silver Based Molecules Containing 5,5′-Dimethyl-2,2′-bipyridine and 2,2′-bipyridine

Abstract

The reaction of AgBF₄ with 5,5′-dimethy-2,2′-bipyridine and 2,2′-bipyridine yields three previously unreported compounds. The molecular structures of these compounds were obtained by single-crystal X-ray diffraction. Crystallization of 1 occurs in the centrosymmetric triclinic space group P-1 (No. 2) with a = 13.0069(6), b = 13.5903(6), c = 13.9489(6); and α = 95.677(2), β = 98.995(2), γ = 101.716(2) and Z = 6. Crystallization of 2 occurs in the centrosymmetric monoclinic space group C2/c (No. 15) with a = 23.413(3), b = 11.2116(13), c = 13.0653(13) and β = 123.074(3), and Z = 4. Crystallization of 3 occurs in the centrosymmetric triclinic space group P-1 (No. 2) with a = 12.6843(12), b = 12.8834(13), c = 12.9887(13), and α = 96.172(5), β = 95.149(5), γ = 98.051(6) and Z = 2. Details of the synthesis and the structural characterization of the title compounds are presented and discussed.

Graphical Abstract

The organic ligands 5,5′-dimethyl-2,2′-bipyridine and 2,2′-bipyridine, were used to synthesize three new complexes with AgBF₄, whose structures are dependent on the type of solvent used in the reaction as well as solvent of crystallization.
