Self‐assemblies of N₂O₄ donor Schiff base ligands, that is, N,N′‐Bis(3‐ethoxysalicylidenimino) 1, 3‐diaminopropane (H₂L^OEt) with cadmium acetate salts in presence of auxiliary co‐ligands thiocyanato/azido/chloride allow the formation of three anion control complexes, specifically, [Cd₂L^OEt(μ_1,3‐SCN)(η¹‐SCN)]_n (1), {Cd₄(L^OEt)₂(μ_1,1‐N₃)₃(η¹‐N₃)]₂ (2) and [Cd₂(L^OEt)(Cl)₂.CH₃OH].CH₃OH] (3). Crystal structures of complexes 1–3 were determined by single‐crystal X‐ray diffraction studies. The single‐crystal X‐ray diffraction analysis confirmed that complex 1 is an one‐dimensional polymeric chain in which Cd(II) ions are bridged by one thiocyanate group bonding in an end‐to‐end fashion. Complex 2 is a centrosymmetric octanuclear complex with double end‐on azide (μ_1,1‐N₃⁻) as linker. On the other hand, 3 is a dinuclear complex with terminally bound Cl⁻ ions. Analysis of the structure revealed that all the complexes possess a 4‐membered Cd₂ (μ₂‐O)₂ core fastened by the combined coordination action of a doubly deprotonated ligand. Complexes 1–3 have been successfully characterized by elemental analyses, IR and UV‐Vis spectroscopy. The luminescent properties of complexes 1–3 have been studied in DMSO solution. The antibacterial and antibiofilm potential for complexes 1–3 were investigated against Gram‐positive and Gram‐negative bacterial strains. Intermolecular interactions with respect to percentages of hydrogen bonding of cadmium complexes were quantified by Hirshfeld surface.
