Syntheses and structures of mono-, di- and tetranuclear rhodium or iridium complexes of thiacalix[4]arene derivatives

摘要

The reactions of [Cp*MCl2](2) (Cp* = eta(5)-C5Me5, M = Rh, Ir) with thiacalix[4]arene (TC4A(OH)(4)) and tetramercaptothiacalix[4] arene (TC4A(SH)(4)) gave the mononuclear complexes [(Cp*M){eta(3)-TC4A(OH)(2)(O)(2)}] and the dinuclear complexes [(Cp*M)(2) {eta(3):eta(3)-TC4A(S)(4)}] respectively, while the analogous reactions with dimercaptothiacalix[4] arene (TC4A(OH)(2)(SH)(2)) produced the tetranuclear complexes [(Cp*M)(2)(Cp*MCl2)(2)-{eta(3):eta(3):eta(1):eta(1)-TC4A(O)(2)(S)(2)}].
