A binuclear bis{bis(dimethylphosphino)methane}disilver(I) complex with weakly bonded hexafluoroacetylacetonato ligands

Abstract

. Can. J. Chem. 72, 1605 (1994). The new complex [Ag2(hfac)2(p-dmpm)2] (hfac = hexafluoroacetylacetonato, dmpm = Me2PCH,PMe,) has been prepared and characterized both spectroscopically and by an X-ray structure determination (orthorhombic, Pbca (No. 61 [Traduit par la redaction]

Thermodynamic and spectroscopic studies on the complexation of silver(I) by mixed phosphorus–nitrogen ligands in dimethyl sulfoxide and propylene carbonate

“…31 P-{ 1 H} NMR spectra recorded at 228 K for all Ag()-P-N systems at R c = 2.0 show two doublets and 31 P-107 Ag coupling constants (430-439 Hz) are indicative of two equivalent P atoms coordinated to the metal ion. 7,9,11, [23][24][25][26][27][28][29][30][31] In addition, IR solution spectroscopy on [Ag(ppye) 2 ] ϩ shows the pyridine-ring stretching absorption at 1599 cm Ϫ1 , practically coincident with that at 1598 cm Ϫ1 observed both in Nujol mull and in dichloromethane for the bis-chelate [Ag(ppye) 2 ]-[PF 6 ] 2 complex. 11 Thus all of the results obtained at R c = 2.0 suggest that in [Ag(P-N) 2 ] ϩ the ligands also behave as bidentate.…”

Alcohol‐Assisted CVD of Silver Using Commercially Available Precursors

“…[5] Most recent developments in this field are attained using silver thin films. [5,6] Other technologically relevant applications of silver thin films include the surface-plasmon enhancement of fluorescence, luminescence and Raman scattering, [7,8] high temperature superconducting systems, [9] anti-bacterial layers, [10] absorbers for infrared sensors, [11] waveguides, [12] and catalysis. [13,14] Silver thin films are mostly grown by physical vapor deposition (PVD), electrochemical deposition, and electroless methods.…”

“…Nevertheless, the CVD of silver is repeatedly reported to be difficult. [9,[15][16][17] Reasons for perceived problems are the low thermal stability and low volatility of silver precursors, motivating the synthesis and evaluation of several new families of silver complexes. [9,[15][16][17][18][19][20][21] However, recent developments in the precursor delivery system circumvent the necessity of thermally stable and highly volatile precursors.…”

[9,[15][16][17][18][19][20][21] However, recent developments in the precursor delivery system circumvent the necessity of thermally stable and highly volatile precursors. [22] Among these processes are aerosol-assisted (AA) CVD, which uses a solvent that does not decompose on the substrate during the deposition, [23] and direct liquid injection (DLI) CVD [2] which employs liquid precursors.…”

CVD of AgI Complexes with Tertiary Phosphines and Perfluorinated Carboxylates—A New Class of Silver Precursors

“…Organometallics of Ag I b-diketonates and alkenes [Ag(hfac)(R)] (R = C n H m , where n = 6± 8, m = 10±14) revealed better volatility than coordination compounds, but they decompose during sublimation. [13] Silver(I) b-diketonates (trifluoracetylacetonate, hexafluoracetylacetonate) do not sublime easily. This imposes complications in the usage of these compounds as CVD precursors.…”
