The reaction of [{η 5 -Cp′′′Co} 2 {μ,η 4:4 -toluene}] with yellow arsenic yields the arsenic-rich As n ligand complexes [{Cp′′′Co(μ,η 2:2 -As 2 )} 2 ] ( 1 ), [(Cp′′′Co) 4 (μ 4 ,η 4:4:2:2:1:1 -As 10 )] ( 2 ) and [(Cp′′′Co) 3 (μ 3 ,η 4:4:2:1 -As 12 )] ( 3 ), which were comprehensively characterized.

| Summary: | The reaction of [{η

{μ,η
4:4
-toluene}] with yellow arsenic yields the arsenic-rich As
n
ligand complexes [{Cp′′′Co(μ,η
2:2
-As

)}

] (

) and [(Cp′′′Co)
3
(μ

,η
4:4:2:1
-As
12
)] (

), which were comprehensively characterized. The molecular structure of
1
show a triple-decker complex with two As
2
units forming the middle-deck; compound
2
contains an all-arsenic As
10
analogue of dihydrofulvalene in the molecular structure. The As
12
ligand in
3
represents the largest As
n
ligand complex reported so far.
A triple decker complex of cobalt is able to consume As
4
moieties of yellow arsenic to built-up the to-date largest known As
n
ligands. |
