The title metallopeptide consists of two divalinyl peptides attached to the carboxylate groups of the ruthenium polypyridyl complex. [Ru(bpy)(2)L](2+): bpy = 2,2'-bipyridine; L = 3,5-dicarboxy-2,2'-bipyridine. The charged ruthenium complex is water soluble and is shown by variable temperature, and 2-D NMR to consist a parallel arrangement of interacting, extended peptide strands that ir reminiscent of the beta-sheet structure. Circular dichroism results support this assignment.
