Bis[4-(dimethylamino)pyridine-κN¹]silver(I) nitrate dihydrate

Abstract

The title compound, [Ag(C(7)H(10)N(2))(2)]NO(3).2H(2)O or [Ag(dmap)(2)]NO(3).2H(2)O, where dmap is 4-(dimethylamino)pyridine, has a distorted linear coordination geometry around the Ag(I) 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 Ag(I) 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.

“…The Ag–N bond length [211.4(3) pm] is found in the same region as for [Ag(DMAP) 2 ][PF 6 ] [211.9(3) pm]20,21 at the shorter end of values reported for silver adducts with heterocyclic N‐donors. [20 and literature cited therein] The coordination around silver is quasi‐linear [178.5(1)°] as to be expected for d 10 derivatives.…”

“…A CSD search [24] revealed 333 structures for bpym with different transition metals while only four Ag(I) structures were found: [Ag 4 (hfac) 4 Table 1. The Ag-N bond distances (2.32 to 2.55 Å) are longer than those found for L-Ag-L linear compounds [18,19] and are correlated to small N-Ag-N chelation angles for all these compounds (65 to 72°).…”

Silver Compounds in Synthetic Chemistry. Part 8. Complexes of Perfluoroorgano Silver(I) Derivatives with 4‐Dimethylaminopyridine (DMAP)

“…[17] Earlier studies [18] revealed that in solution especially perfluoroalkylsilver derivatives undergo complex exchange equilibria involving a "neutral" species, AgR f , an "ionic" species, Ag[Ag(R f ) 2 ], and a "polymeric" form, [ 4-Dimethylaminopyridine (DMAP), additionally to its excellent catalytic activity in organic transformations, [19] exhibits positive features making among many other metal compounds silver derivatives easily crystallizable. [20,21] All attempts to obtain structural data for perfluoroalkylsilver(I) compounds have been limited to few examples. [2,22,23] Also the number of publications dealing with structurally characterized perfluoroarylsilver(I) derivatives is low.…”
