“…† The use of tri-and tetramethylcyclopentadiene rather than mono-and dimethylcyclopentadiene, respectively, eliminates the possibility of isomerism. Reports on unsymmetrically substituted fulvalene-tetracarbonyl-diruthenium compounds are otherwise scarce, another example being an indenylanalogue, 35 where the corresponding "dihydrofulvalene" is stable enough to be prepared by Negishi-coupling. 36 Like 1, compounds 2 and 3 are bright yellow solids, sparingly soluble in most organic solvents.…”

In a Molecular Solar-Thermal Energy Storage (MOST) system, solar energy is converted to chemical energy using a compound that undergoes reversible endothermic photoisomerization. The high-energy photoisomer can later be converted back to the parent compound and the excess energy is released as heat. One of the most studied MOST systems is based on fulvalene-tetracarbonyl-diruthenium, and this paper demonstrates, for the first time, the possibility to tune the photochemical properties of this system by positive steric hindrance working on the fulvalene unit.

A study of the scope and limitations of varying the ligand framework around the dinuclear core of FvRu2 in its function as a molecular solar thermal energy storage framework is presented. It includes DFT calculations probing the effect of substituents, other metals, and CO exchange for other ligands on ΔHstorage . Experimentally, the system is shown to be robust in as much as it tolerates a number of variations, except for the identity of the metal and certain substitution patterns. Failures include 1,1',3,3'-tetra-tert-butyl (4), 1,2,2',3'-tetraphenyl (9), diiron (28), diosmium (24), mixed iron-ruthenium (27), dimolybdenum (29), and ditungsten (30) derivatives. An extensive screen of potential catalysts for the thermal reversal identified AgNO3 -SiO2 as a good candidate, although catalyst decomposition remains a challenge.

Thermal treatment of dihydrooctamethyl-s-indacene with Ru3(CO)12 afforded the trinuclear and tetranuclear complexes Ru3(η5:η5:η2-C20H24)(CO)7 (1) and Ru4(η5:η4:η1-C20H24)(μ-CO)2(CO)7 (2), via intramolecular sp3 C−H bond activation, and the mononuclear complex Ru(η5-C20H25)(CO)2Cl (3), which might be formed via chlorination of a terminal hydride complex during column chromatography. Reaction of 1,2,3,4,7-pentamethylindene with Ru3(CO)12 also yielded the tetranuclear complex Ru4(η5:η3:η2-C14H16)(CO)9 (4) via the same sp3 C−H bond activation, together with the dinuclear complex [(η5-C9H2Me5)Ru(CO)]2(μ-CO)2 (5). In contrast, reaction of 4,7-dimethylindene with Ru3(CO)12 gave only the dinuclear complex [(η5-C9H5Me2)Ru(CO)]2(μ-CO)2 (6). The molecular structures of all six complexes have been determined by single-crystal X-ray diffraction analysis.
