cis-Dichlorobis(bipyridine)ruthenium(II) is the coordination complex with the formula RuCl2(bipy)2, where bipy is 2,2'-bipyridine. It is a dark green diamagnetic solid that is a precursor to many other complexes of ruthenium, mainly by substitution of the two chloride ligands.[1] The compound has been crystallized as diverse hydrates.

Synthesis and structure

The complex is prepared by heating a DMF solution of ruthenium trichloride and bipyridine.[2]

With octahedral coordination geometry, the complex exists exclusively as the chiral cis isomer. The corresponding Ru(III) salts are also known.[3]
