Four　novel　coordination　polymers　(CPs),　[Co(adp)0.5(biimpy)(NO3)]n　(1),　[Cu(adp)0.5(biimpy)(H2O)]n　(2),　{[Zn(adp)(biimpy)]·2H2O}n　(3),　and　[Cd1.5(adp)1.5(biimpy)]n　(4),　were　synthesized　hydrothermally　using　adipic　acid　(H2adp)　and　2,6-bis(1H-imidazol-1-yl)pyridine　(biimpy)　as　mixed　ligands.　Single-crystal　X-ray　diffraction　revealed　diverse　architectures:　a　two-dimensional　(2D)　layer　(1),　a　three-dimensional　(3D)　interpenetrating　framework　(2),　a　one-dimensional　(1D)　meso‑helical　chain　(3),　and　a　trinuclear　Cd-based　1D　chain　(4).　The　observed　structural　diversity　is　mainly　attributed　to　the　varying　coordination　preferences　of　the　d10　metal　centers.　Powder　X-ray　diffraction　(PXRD)　confirmed　the　phase　purity　of　the　bulk　samples,　while　thermogravimetric　analysis　(TGA)　demonstrated　their　thermal　stability.　Magnetic　property　investigations　reveal　that　compounds　1　and　2　exhibit　weak　antiferromagnetic　behavior.　Solid-state　photoluminescence　studies　showed　that　compounds　3　and　4　exhibit　strong　violet　emissions　at　420　nm　and　418　nm,　respectively,　upon　excitation　at　380　nm,　attributed　to　ligand-to-ligand　charge　transfer.　These　results　demonstrate　that　the　rational　selection　of　metal　centers　and　mixed-ligand　strategies　is　an　effective　approach　for　constructing　structurally　diverse　and　functionally　luminescent　coordination　materials.　©　2025　Elsevier　B.V.
