Dalton communications. A zwitterionic cluster compound: synthesis and characterisation of the triphenylphosphoniocyclo-pentadienide derivative [Ru6C(CO)14(η5-C5H4PPh3)]

Abstract

The crystal and molecular structure of the zwitterionic octahedral cluster, [Ru₆C(CO)₁₄(η⁵-C₅H₄PPh₃)], prepared from the reaction of [Ru₆C(CO)₁₇] with trimethylamine N-oxide in the presence of triphenylphosphoniocyclopentadienide, has been established by low-temperature single-crystal X-ray diffraction analysis, and shows intermolecular interactions typical of zwitterionic compounds.
