trans-Dichloridotetrakis(4-methoxypyridine-κN)ruthenium(II)

Abstract

The structure of the title complex, [RuCl2(C6H6NO)4], exhibits point group symmetry \overline{4}. The structure exhibits disorder around a \overline{4} axis. The 4-methoxypyridine ligands have a propeller-like arrangement around the RuII atom at 52.0 (3)° from the RuN4 plane.

“…neutral tetrakis(DMAP) product, a general synthesis was followed, as described for trans-[RuCl 2 (pyrazine-�N) 4 ] (Carlucci et al, 2002), where [RuCl 2 (dmso) 4 ] and four equivalents of a pyridyl-based ligand are heated in toluene for multiple hours. This method has yielded trans-[RuCl 2 (NN) 4 ] compounds with NN = 4-methoxypyridine (Reinheimer et al, 2023) or pyrazine (Nesterov et al, 2012). Rath and co-workers explored the effects of solvent polarity on the substitution of dmso and used a water/methanol solution of [Ru(dmso) 4 Cl 2 ] and two equivalents of pyridine to form cis,cis,cis-[RuCl 2 (dmso-�S) 2 (py) 2 ] (Trivedi et al, 2010).…”
