X-ray Crystal Structures of Discrete and Polymeric Silver Based Molecules Containing 4,4′-Dimethyl-2,2′-Bipyridine and 2,2′-Bipyridine

The reaction of AgBF 4 with 4,4′-dimethyl-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 monoclinic space group C 2/ c (No. 15) with a = 23.407(3), b = 10.7552(13), c = 13.9332(17); and β = 111.893(2) and Z = 8. Crystallization of 2 occurs in the centrosymmetric orthorhombic space group Pbca (No. 61) with a = 11.178(3), b = 23.590(6), c = 29.339(8) and Z = 8. Crystallization of 3 occurs in the centrosymmetric monoclinic space group P 2 1 / c (No. 14) with a = 11.2250(6), b = 8.7713(5), c = 15.4048(8), and β = 109.333(2) and Z = 4. Details of the synthesis and the structural characterization of the title compounds are presented and discussed. Index Abstract The organic ligands 4,4′-dimethyl-2,2′-bipyridine and 2,2′-bipyridine, were used to synthesize three new complexes with AgBF 4 , whose structures are dependent on the type of solvent used in the reaction as well as solvent of crystallization.
