Reference of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

Reaction of hexa(hydroxybutenyl)benzene, 1a, and its FeCp+ complex, 1b, with halogeno-polypyridine in DMSO in the presence of KOH yields the hexapolypyridine ligands 2-4 and their iron-centered complexes 5-7. The hexaligands 3 and 4 were metallated using Ru(bipy)2Cl2 and Ru(terpy)Cl3, respectively, which gave correct yields of the hexaruthenium complexes 8 and 9. The iron-centered core 1b also reacted with [Ru(bipy)2(4-chloro-bipy)]2+(PF6 -)2 to give the hexaruthenated heptanuclear complex 11. Full characterizations including various mass spectrometry techniques verified the proposed structures. CNRS-Gauthier-Villars.
