Synthetic access to the [R′S(NR) 3 ] − and [S(NR) 4 ] 2− ions (R = tert ‐butyl, R′ = Me) permits the study of their coordination behavior. As isoelectronic NR analogues of the sulfonate [RSO 3 ] − and sulfate SO 4 2− ions they contain nitrogen donor atoms in the periphery of the ligand. The barium metal complexes of these ligands are soluble molecular‐contact ion pairs rather than solid‐state aggregates. Tripodal coordination is precluded by steric requirements, and the bidentate coordination mode is favored.
