Reactivity and spectroscopy of the {Ru(DMAP)5} fragment: An {Ru(NH3)5} analogue
Reaction of trans-Ru(DMSO)4Cl2 with DMAP (DMAP = 4-dimethylaminopyridine) yields the yellow [Ru(DMAP)6]2+ cation in good yield. The crystal and molecular structure of [Ru(DMAP) 6]Cl2·6CH3CH2OH was determined by X-ray diffraction methods. The complex crystallizes in the trigonal R3 space group with a...
