A serendipitous result was obtained when too much rubidium was used in the synthesis of Rb 3 As 7 in a niobium tube: the surprising product is a complex containing the anion [NbAs 8 ] 3− 1 . This is the first example of an octacycle acting as an η 8 ‐ligand to coordinate a metal atom at its center. With Rb + , one‐dimensional chains ∞ 1 [Rb{NbAs 8 }] 2− are formed, even though the strong complex formers 2,2,2‐crypt and ethylenediamine were present during the crystallization.
