Ruthenocene, [Ru(5C5H5)2], is a relatively stable compound that can be handled and stored at room temperature. 1 In contrast, rhodocene, [Rh(5C5H5)2], is only stable under "extreme" conditions (e.g. 196C). At room temperature, rhodocene dimerises to give a species with formula [Rh(C5H5)2]2.2 (a) Draw chemical structures for [Ru(5C5H5)2],[Rh(5C5H5)2] and [Rh(C5H5)2]2. (b) For [Ru(5C5H5)2] and [Rh(5C5H5)2], draw the frontier molecular orbital diagrams. (c) Explain the different chemical properties observed for ruthenocene and rhodocene at room temperature
