Synthesis, Structure, and Properties of a Novel Heterooctametallic Complex Containing a Cyclic Ru4 Ni4 Core.

From two to five: A mononuclear Ru complex of salicylaldehyde thiosemicarbazone (H3 saltsc, 1), in which only two of the coordination sites of 1 participate in bonding ([Ru(bpy)2 (H2 saltsc)]ClO4 ), could be used to synthesize the cyclic complex cation [{Ru(bpy)2 (saltsc)}4 Ni4 ]4+ (bpy=2,2'-bipyridine). Its formation demonstrates that the Ru complex can act as an N,N,O donor ligand for the construction of polynuclear complexes.
