Bis[4-(dimethylamino)pyridine-κN1]silver(I) nitrate dihydrate
Artikel i vetenskaplig tidskrift, 2009

The title compound, [Ag(C7H10N2)2]NO3·2H2O or [Ag(dmap)2]NO3·2H2O, where dmap is 4-(dimethylamino)pyridine, has a distorted linear coordination geometry around the AgI ion. A novel pattern of water-nitrate hydrogen-bonded anionic strands is formed in the c direction, with the cationic [Ag(dmap)2]+ monomers trapped between them. The AgI ion and the nitrate group atoms, as well as the water molecules (including the H atoms), are on a crystallographic mirror plane (Wyckoff position 4a). The influence of bulky methyl substituents in position 4 of the 4-(dimethylamino)pyridine ligand on packing is discussed. The absolute structure was determined unequivocally.
