| Summary: | 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.
The reaction of [{η

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

), 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. |
