| Popis: | Three Zn II /Cd II -coordination polymers based on 2-propyl-4,5-imidazoledicarboxylate (H 3 pimdc), namely, [Zn(Hpimdc)H 2 O] n ( 1 ), [Cd(H 2 pimdc) 2 ] n ( 2 ) and [Cd 2 (Hpimdc) 2 (bbi) 0.5 (H 2 O) 2 ] n [bbi = 1,10-(1,4-butanediyl)bis(imidazole)] ( 3 ), have hydrothermally been synthesized, which exhibit a systematic dimensional variation by changing the metal ions or introducing the auxiliary ligand. Complex 1 is a 1D zig-zag polymeric chain, which is finally extended into a 3D supramolecular network through R 4 4 (12) O–H⋯O H-bonding rings. Complex 2 shows a 2D layer comprised alternately arranged left- and right-handed helical chains. Complex 3 features a rare (3,3)-connected 8 3 network with opposite chiral layers in a slipped ABAB fashion. The photoluminescent properties and thermal stabilities of three complexes are also discussed. |
