Crystal structures of silver(I) benzoate and p-hydroxybenzoate

Synthesis, X-ray crystal structure, anti-fungal and anti-cancer activity of [Ag2(NH3)2(salH)2] (salH2=salicylic acid)

“…Such hydrogen-bonding interactions have been implicated in the formation of some complexes exhibiting auriophilicity [8]. In contrast to the structure of [Ag 2 (NH 3 ) 2 (salH) 2 ], the silver(I) benzoates with no ortho-hydroxyl substituents deviate markedly from planarity [9]. The Ag-Ag bond (3.069 A) in [Ag 2 (NH 3 ) 2 (salH) 2 ] is slightly longer than that found in [Ag 2 (salH) 2 ] (2.855 A) implying that the ligand architecture of the syn-syn bridged dimers in the latter species facilitates a closer approach of the silver ions [5,6].…”

Synthesis, X-ray structure and antimycobacterial activity of silver complexes with α-hydroxycarboxylic acids

“…3). The polymeric structure of AgMand is type III, based on the classical bis(carboxylate-O,O 0 ) dimer [23]. Oxygen atoms of the carboxylate groups from different mandelate ligands are bonded to two Ag(I) atoms in a syn-syn mode [24] with the distances 2.222(3) and 2.2237(3Å ) for Ag-O2 i and Ag-O1, respectively, arranged as an eight-membered ring or as Ag-bis(O,O 0 -carboxylate)-Ag i .…”

Soft Luminescent Materials Based on Ag(I) Coordination Complexes

“…-[(bpy-R) 3 benzoates may act as counterions [9,10] as well as monodentate [11] or bidentate [12] ancillary ligands, yielding thus very different stereochemical arrangements. Furthermore, the easiness of functionalization with long alkyl chains into the benzoate ions, affords a simple way to increase the aliphatic part in the molecular structure of the resulting complexes [13]. Therefore, as an extension of our work regarding soft materials based on Ag(I) complexes, herein, we report on the synthesis and characterization of a new liquid-crystalline complex, Bz12, containing a 2,2 -bipyridine functionalized with several long alkyl chains as main ligand and the 3,4,5-dodecyloxybenzoate as complementary ligand.…”

“…In particular, dimeric [13] Ag(I) alkyloxybenzoates p 1 and p 2 , were obtained starting from the appropriate benzoic acid derivatives [14] adapting a synthetically procedure reported in the literature [15] corresponding complexes Bz1 and Bz12 were obtained by stirring for 16 hours at room temperature (r.t.) in a vessel protected by light, a solution in chloroform of the two precursors [16], respectively the Ag(I) benzoates (p 1 or p 2 ) and the proper bipyridinic ligands (bpy-C 1 or bpy-H 12 ) (Scheme 1).…”
