Figure 5 Some examples of silver complexes with Schiff base macrocycles.

Silver(I) complexes with macrocyclic ligands that possess O/N/S as donor atoms have been studied extensively 1474-1533 in Figure 16 a selection of some silver complexes with this type of ligands can be seen. 

An extension of the research on silver complexes with Lewis base-functionalized mono(A-heterocyclic carbene) ligands has been made toward the better-studied and stronger coordinating phosphine systems. The reaction of a diphenylphosphine-functionalized imidazolium salt with silver oxide in dichloromethane affords a trinuclear silver carbene complex 50, as confirmed by electrospray-ionization mass spectrometry.96,97 Metathesis reaction of 50 in methanol using silver nitrate gives 51 in 33% yield. The crystal structures of 51 were found to be different when different solvents were used during crystallization (Scheme 12).97 One NO3- anion was found to be chelated to... 

For the series of silver complexes with cyanide, the C-N stretching vibrations are observed as follows. The species containing three or four cyanide ions are observed only in solutions containing high concentrations of CNT...

The determination of iodide with ion-selective electrodes is possible with commercial sensors often based on ion conducting Ag2S—Agl solid membranes [57]. A PVC membrane-based sensor employing a silver complex with thiourea derivatives has been reported by El Aamrani et al. [202]. Interference from thiocyanate and bromide was investigated and a limit of detection in the nanomolar range was determined. A study assessing the performance... 

For the Ag grids a slight broadening of the resonances is observed at low temperature, which can be attributed to a dynamic process, probably due to the marked tendency for decoordination of the silver complexes with N-donor ligands. 

The complexes of silver(I) ions with substituted pyridines are well known and some representative thermodynamic data for their formation are included in Table 13.81-83 Several attempts have been made to correlate the stability of the silver complexes with the basicity of the substituted pyridines.81,82 In general, a linear relationship between the logarithm of the formation constants and the pKa of the free bases was found to exist. 

Silver(I) complexes can also be obtained when the pyridyl N becomes quatemized, if the aliphatic group contains an amine. Thermodynamic data for silver complexes with ligands of the type C5H5N+(CH2) NH (n = 2-5) are given in Table 16.88,89... 

From the bond distances in Table 28,188-192 it can be seen that the Ag—P distances remain relatively constant, whilst the Ag—X distance varies depending on the halide. This was also the case with 1 2 silver complexes with monodentate phosphines. 

The discoloring is likely to be caused by the photoreduction of silver chloride and/or silver phosphate in the skin. X-ray dispersive analysis of skin and other tissues reveals that the granules consist of silver complexed with sulfur and/or selenium. The photoreduced deposits are not removed by the body, and there are no clinical means of removing them.
