Silver m

Both silver (m.p. 962°C, b.p. 2212°C) and gold (m.p. 1065°C, b.p. 2807°C) have characteristic brilliant white and yellow colours in bulk but when finely divided are black or, in the case of gold, can be purple, ruby red or blue. Thus reduction of gold compounds by SnCl2 gives the colloid known as Purple of Cassius , which is used as a ceramic colorant.

In 1986, Dukat and Naumann reported a surprisingly stable silver(m) ion, [Ag(CF3)4], in the form of a mixed silver(i)-silver(m) salt AgI[Agin(CF3)4] 166.221 It was formed upon the facile disproportionation reaction of the silver(i) complex, [Ag(CF3)2], prepared in situ from the treatment of silver(i) salts like silver(i) nitrate or silver(i) acetate with [Cd(CF3)2], according to Equations (2) and (3). 

It is noteworthy to mention that employment of silver(i) trifluoroacetate in place of silver(i) acetate, as in the case of A-confused porphyrin, did not give the desired products. This has been attributed to the better basicity of the acetate anion than the trifluoroacetate, which aided the deprotonation of the three interior GH/NH protons at the carbaporphyrin ligand. Besides, it has been noticed that an excessive amount of silver acetate was required for the synthesis. The mechanism of the silver insertion reaction for this type of ligands was proposed, according to what Bruckner had proposed for the synthesis of silver(m) w -triarylcorroles.218,236 The reaction was suggested to occur via a disproportionation reaction, with the supportive observation of silver deposit formation after the reaction.237... 

Modification of the carbaporphyrin ligands could also be made by the interchange of an exocyclic methine group with a heteroatom such as oxygen. Ligands of this type are referred to as O-confused oxaporphyrins. Silver(m) complexes...

Zrl4 vapour reacts rapidly and reversibly with metallic copper and silver (M) at ca. 200°C to give thick, velvet-like scales of Mq 2sZro.75l3, which are considered to be pseudo-trihalides. Hfl4 vapour only reacts to a small extent with copper and not at all with silver. ... 

Upper respiratory tract irritation bas been observed in bumans at estimated exposure levels of between 0.04 and 0.4 mg silver/m for less than 1 to greater than 10 years. Irritant effects are considered to be related to tbe caustic properties of tbe various silver compounds, ratber than tbe silver itself.
