Ac‐His‐OH and His‐His‐OH were treated with [Re(CO) 3 (H 2 O) 3 ] + to yield two new compounds, which were structurally characterized. Each displays a peptide carboxamido‐N donor. The complex formed with His‐His‐OH uses this group as a bridging, bidentate ligand; the complex resists challenge experiments showing that His‐tags are a good way to deliver the [M(CO) 3 ] + core (M = 99m Tc, Re).
