Linked arene clusters: the interaction of tetracobalt nonacarbonyl with [2.2.2]paracyclophane
Abstract
The thermolysis of [2.2.2]paracyclophane in the presence of an excess of [Co4(CO)12] yields three new arene clusters [{Co4(CO)9}n(C24H24)] (n = 1, 2 and 3): the molecular structures of the mono- and bis-cluster complexes have been established by single crystal X-ray diffraction while the tris-complex has been characterised by spectroscopy.
