Silver carboxylates [Ag(O2CR): R = Me, tBu, 2,4,6-Me3C6H2], fluorocarboxlyates [Ag(O2CRf): rf = c3f7, C6F13, C7F15] and their phosphine adducts [Ag(O2CR)·nPR3′: r = me, tBu, 2,4,6-Me3C6H2, R′ = Me, Ph, n = 2; R = Me, R′ = Me, n = 3; Ag(O2CRf).2PPh3, Rf = C3F7, C6F13, C7F15] have been synthesised, characterised spectroscopically and used as precursors in the aerosol-assisted chemical vapour deposition of silver films. All the phosphine adducts produced films, though in general PMe3 adducts, proved more successful than PPh3 analogues. The fluoro-carboxylates and their PPh3 adducts all generated silver films, though the growth rate for the adducts was lower. All these latter films showed carbon impurities while fluorine was also evident in most cases. The X-ray structure of AgO2CC3F7·2PPh3 is also reported.

The Ag atom in both independent molecules of acetatobis(triphenylphosphine)silver(I), [Ag(C2H3O2)-(C18H 15P)2], is bonded to the triphenylphospine and chelating acetato ligands in a distorted tetrahedral environment. Acetatobis(triphenylphosphine)silver(I) sesquihydrate, [Ag(C2H3O2)(C18H15P) 2].1.5H2O, also crystallizes as two independent molecules, the Ag atoms of which adopt a similar geometry. One [Ag(C2H3O2)-(C18H 15P)2] molecule is linked through a water molecule to another complex molecule, which in turn is linked to the symmetry-related first molecule through the other two water molecules, one of which is disordered, affording a chain structure parallel to the b axis. Bis(μ-acetato)-O,O′:O;O:O-bis[(triphenylphosphine)silver(I)] hydrate, [Ag2(C2H3O2)2(C 18H15P)2].-H2O, comprises two [Ag(C2H3O2)(C18H15P)] moieties; the acetato ligand behaves as a bidentate chelating anion in one complex moiety but as a monodentate anion in the other. The two moieties link through the singly bonded ester O atom into a dinuclear entity. Neighboring dinuclear entities are linked by hydrogen bonds involving their doubly-bonded carboxyl ends with the disordered water molecule to form a zigzag chain along the c axis. In bis(μ-acetato-O:O)bis[(triphenylphosphine)silver(I)] hemihydrate, [Ag2(C2H3O2)2(C 18H15P)2].0.5H2O, the two Ag - Ocarboxyl distances are long enough for the geometry of the Ag atoms to be regarded as being essentially trigonal planar in the two complex units. The dinuclear molecule uses its doubly-bonded O atoms to link with the disordered water molecule to afford a hydrogenbonded tetranuclear entity.
