  摘要：

  A series of Ag(I) complexes, [Ag(X)L], where X is the anion of 2,2,6,6-tetramethyl-3,5-heptanedione (tmhdH), 2,2,7-trimethyl-3,5-octanedione (tmodH), 2-sila-2,2,6,6-tetramethyl-3,5-heptanedione (tmshdH), 5-mercapto-2,2,6,6-tetramethyl-4-hepten-3-one (S-tmhdH), 5-mercapto-2,2,7-trimethyl-4-octen-3-one (S-tmodH), or 5-amino-2,2,6,6-tetramethyl-4-hepten-3-one (N-tmhdH) and L = triphenylphosphine (PPh3) or tri-n-butylphosphine (PBu3) were prepared by treatment of silver nitrate with either the diketone derivative in the presence of a base or with the preformed sodium salt of the diketone derivative. The thermal properties of the new complexes were investigated for potential application in chemical vapor deposition (CVD) processes. Results of thermogravimetric analysis showed that the vast majority of the silver complexes have little promise for CVD, since the ligands dissociate at elevated temperatures without volatilization. The first ever reported single crystal X-ray diffraction studies of silver complexes, with simple, ancillary, non-fluorinated beta-diketonate supporting ligands, revealed [Ag(tmhd)(PPh3)] (la) to be monomeric and [Ag(S-tmhd)(PPh3)](2) (4a) to be dimeric in the solid state, respectively.
