ring-opening reaction of precursors 1–4 in presence of the [Pd(tmeda)Me2] and [Pd(μ -Cl)(η3-C3H5)]2 starting materials. The Ln}− anionic Schiff bases obtained showed a versatile behavior towards coordination to Pd(II) ion; in 1a–4a the ligand acted as tricoordinate whilst in 1b–3b and 4c, Ln}− acted as mono- and tridentate ligand, respectively. 1a–4a were stable complexes in DMSO‑d6 solution; the dinuclear
