tertiary sulfonamide group, N(SO2R)R′2, can rehybridize to form a M–N bond of normal length even when the group is in a linear tridentate ligand, such as in the new tridentate N(SO2R)dpa ligands derived from di-(2-picolyl)amine (N(H)dpa). N(SO2R)dpa ligands were used to prepare fac-[Re(CO)3(N(SO2R)dpa)](PF6 or BF4) complexes. Structuralcharacterization of the new complexes established that the tertiary
