N-Alkylated derivatives of 1,3,5-triazacyclohexane (tach) are versatile, facially coordinating ligands. We present the syntheses and full characterization of two new complexes of the [(R(3)tach)ReO3](+) type. In these complexes, the tach ligand is readily substituted by bi-and tridentate ligands; hence, they can be considered as sources of the [ReO3](+) motif for Re-VII complexes.
