title: beta-Diiminato complexes of arsenic including the formally AsI compound [As3L3] [L = [N(C6H3Pri2-2,6)C(H)]2CPh].
abstract: The reaction of the potassium beta-diiminate KL (L = [[N(Ar)C(H)](2)CPh](-); Ar = C(6)H(3)Pr(i)(2)-2,6) with AsI(3) gave [AsI(2)L] (1), which upon reduction with KC(8) produced [(kappa(1)-L)(2)As-As[double bond, length as m-dash]As(kappa(2)-L)] (2), having a unique bent chain of the three arsenic atoms in the formal oxidation states +2, 0 and +1.
