Synthesis, Structure, and Properties of a Novel Heterooctametallic Complex Containing a Cyclic Ru4Ni4 Core

Abstract

From two to five: A mononuclear Ru complex of salicylaldehyde thiosemicarbazone (H3saltsc, 1), in which only two of the coordination sites of 1 participate in bonding ([Ru(bpy)2(H2saltsc)]ClO4), could be used to synthesize the cyclic complex cation [{Ru(bpy)2(saltsc)}4Ni4]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.
