Abstract

Reactions of the cyclic tetraphosphine (CyP)4 with arsenium or stibenium cations (R2Pn+, Pn = As, Sb and R = Cl, Ph) give salts of the new cationic frameworks [(CyP)4(AN)]+, [(CyP)4(SbCl2)]+ and [{(CyP)4}2(Sb2Cl2)]2+. The cations can be viewed as coordination complexes of a cyclophosphine ligand on a pnictenium cation, or a cyclo-2,3,4-triphosphino-1-pnictino-1-phosphonium cation, representing the first branched cyclic pnictogen framework, and examples of tertiary phosphonium centers with As–P or Sb–P bonds.
