Hexaethylbenzene complexes of ruthenium and manganese — X-ray crystal structures and NMR spectra of [(HEB)2Ru2(-Cl)3][C5(CO2Me)5], [(HEB)Ru(H2O)3][BF4]2, (HEB)RuCl2[P(OMe)3], trans-RuCl2(PMe3)4, and (HEB)Mn(CO)2Br

Hexaethylbenzene (HEB) and [(p-cymene)RuCl 2 ] 2 react in the melt to yield [(HEB)RuCl 2 ] 2 (6), the NMR spectra of which reveal the presence of [(HEB) 2 Ru 2 (µ-Cl) 3 ]Cl in solution. In [(HEB) 2 Ru 2 (µ-Cl) 3 ][C 5 (CO 2 Me) 5 ] (7), the cation has D 3 h symmetry with alternating proximal and distal ethyl groups. Bridge cleavage of 6 with trimethyl phosphite or with trimethylphosphine gives (HEB)RuCl 2 [P(OMe) 3 ] (9) or (HEB)RuCl 2 (PMe 3 ) …
