Chlorido(4,4′-dimethoxy-2,2′-bipyridine)(1,4,7-trimethyl-1,4,7-triazacyclononane)ruthenium(II) perchlorate acetonitrile disolvate and aqua(4,4′-dimethoxy-2,2′-bipyridine)(1,4,7-trimethyl-1,4,7-triazacyclononane)ruthenium(II) bis(perchlorate) dihydrate

Abstract

The title complexes, [RuCl(C9H21N3)(C12H12N2O2)]ClO4.2C2H3N, (I), and [Ru(C9H21N3)(C12H12N2O2)(H2O)](ClO4)2.2H2O, (II), display similar structures with the Ru atom in a distorted octahedral environment. In the crystal packing of the chloride complex, (I), the Ru complex molecules are held together in pairs through CH...Cl interactions of the 4,4´-dimethoxy-2,2´-bipyridine and chloride ligands. In the case of the aqua complex, (II), hydrogen bonding affords a tetrameric hydrogen-bonded network. These two structures are the first examples of complexes with the {Ru(1,4,7-trimethyl-1,4,7-triazacyclononane)} motif and an electron-rich substituted 2,2´-bipyridine ligand.
