β-Diiminato complexes of arsenic including the formally AsI compound [As3L3] [L = {N(C6H3Pri2-2,6)C(H)}2CPh]

Abstract

The reaction of the potassium β-diiminate KL (L = [{N(Ar)C(H)}₂CPh]⁻; Ar = C₆H₃Prⁱ₂-2,6) with AsI₃ gave [AsI₂L] (1), which upon reduction with KC₈ produced [(κ¹-L)₂As–AsAs(κ²-L)] (2), having a unique bent chain of the three arsenic atoms in the formal oxidation states +2, 0 and +1.
