Abstract
An X-ray crystallographic study of adducts of trialkylphosphine selenides w ith > 1 equivalent of diiodine reveals that solid (Bu3PSeI3)-P-t consists o f cation pairs [((Bu3PSe)-P-t)(2)I+](2) intercalated between I-5(-) layers and that solid R2R'PSeI7 (R = Bu-t or Pr-i, R' = Pr-i) contains [R2R'P-Se-I ](+) cations with weak secondary I ... I interactions to polyiodide network s.
