Abstract
The synthesis, isolation and characterisation of two new cluster complexes [Ru6C(CO)14(C16H15NH2)] 1 and [Ru6C(CO)14(C16H15Br)] 2 are reported. An X-ray crystallographic study has shown that the 4-amino[2.2]paracyclophane ligand in the former compound is coordinated via its aniline ring in the novel µ3-η1∶η2∶η2 mode. In contrast, correlation 1H NMR shows that the 4-bromo[2.2]paracyclophane ligand in the latter compound is coordinated via the unsubstituted ring. These observations are consistent with the relative activating and deactivating effects of the substituents.Keywords
