Abstract

Six coordination polymers (CPs), namely, [Ag(tmb)]n (1), [Cu(tmb)2(H2O)]n (2), [Eu(HCOO)(tmb)2]n (3), [Ag(bimb)(Hbimb)]n (4), [Cu(bimb)2]n (5) and [Eu(bimb)3]n (6) (Htmb = 4-((1H-1,2,4-triazol-1-yl)methyl)benzoic acid), Hbimb = 4-((1H-benzo[d]imidazol-1-yl)methyl)benzoic acid), have been successfully synthesized under similar solvothermal conditions and characterized by elemental analysis, IR, thermogravimetric analysis and single-crystal X-ray diffraction. 3-D complex 1 presents a binodal (3,6)-connected rutile topology with the Schläfli symbol (42·610·83) (4·62)2. Previously reported complex 2 shows a 3-D framework of pcu topology, in which the inorganic ⋯Cu-O-Cu-O⋯ chains are connected to each other through the tmb- ligands. In 3, Eu(iii) atoms are connected by carboxylate groups to form a double-helical chain, which further expands to a 3-D framework of tsi topology with the Schläfli symbol (36·416·56). Complex 4 exhibits a 1-D chain structures which are further connected by O-H⋯O hydrogen bonding and π⋯π interactions to form a 3-D supramolecular framework. Complex 5 features a two-dimensional 44 layer. In 6, Eu3+ ions are bridged by bimb- ligands to form a 1-D three-strand double-helical chain which is further connected by ligands to produce a 2-D layer with a 4·82 topology. The different structural dimensions of the six complexes (1-6) are closely related to the steric effect of the triazole ring or benzimidazole ring in the ligands. Furthermore, the fluorescence properties of 1, 3, 4, and 6 are studied in the solid state at room temperature.
