“…1 Later on, this reaction was studied further by Lenher, 2 and finally Caldwell and Eddy claimed that the product of the reaction can be used for glass coloring purposes. 3 However, it was only in the early 1980s when the first structure elucidations revealed the nature of the reaction products, 4 which turned out to be gold oxoselenates(IV). A similar story can be told for sulfates of gold, which were also investigated a long time ago by Schottl€ ander, 5 but which lacked characterization even until 2001, when we were able to prepare the binary gold(II)sulfate Au 2 (SO 4 ) 2 that shows a metalÀmetal bonded [Au 2 ] 4+ dumbbell, which is coordinated by two chelating and two mondentate sulfate groups.…”

“…The first systematic investigations of gold compounds containing complex oxoanions can be traced back to 1827 when Mitscherlich reported that elemental gold dissolves in concentrated selenic acid . Later on, this reaction was studied further by Lenher, and finally Caldwell and Eddy claimed that the product of the reaction can be used for glass coloring purposes . However, it was only in the early 1980s when the first structure elucidations revealed the nature of the reaction products, which turned out to be gold oxoselenates(IV).…”

“…Later, Lenher repeated the reaction and claimed that the yellow compound he obtained was Au 2 (SeO 4 ) 3 . Coldwell and Eddy investigated the reaction in more detail in 1949 and pointed out that Au 2 (SeO 4 ) 3 may be used in glass coloring processes .…”

“…Accord-The oxidation of elemental gold with concentrated selenic acid is well known for a long time [1]. Formerly, Au 2 (SeO 4 ) 3 was assumed to be the reaction product and this substance has been shown to be useful in glass coloring processes [2,3]. However, roughly twenty years ago it has been shown that in fact selenites form during the dissolution of elemental gold in selenic acid which have, depending on the specific conditions, the different compositions Au 2 (SeO 3 ) 2 O and Au 2 (SeO 3 ) 2 (Se 2 O 5 ) [4].…”
