(Terpyridine)ruthenium trichloride

(Terpyridine)ruthenium trichloride is the coordination complex with the formula RuCl₃(terpy), where terpy is terpyridine. It is a brown paramagnetic solid that is a precursor to other complexes of ruthenium, mainly by substitution of the chloride ligands. The complex has octahedral geometry.^[1] The synthesis of this complex was reported for the first time in 1980, it was prepared by mixing ruthenium trichloride and terpyridine in ethanol, heating the mixture to reflux conditions^[2] A later synthetic protocol uses a similar approach by heating ruthenium trichloride with a DMF solution of terpyridine.^[3]
