Three novel polymers, {l_brace}[Cd(m-bdc)(L)].H{sub 2}O{r_brace}{sub n} (1), [Co(m-bdc)(L){sub 0.5}(H{sub 2}O)]{sub n} (2) and [Zn{sub 5}(L){sub 2}(p-bdc){sub 5}(H{sub 2}O)]{sub n} (3) based on 1,1'-bis(pyridin-3-ylmethyl)-2,2'-biimidazole (L) ligand and benzenedicarboxylate isomers, have been prepared and structurally characterized. Compound 1 exhibits a 2D architecture with (4{sup 2}.6)(4{sup 2}.6{sup 7}.8) topology, which is synthesized by L and 1,3-benzenedicarboxylate (m-bdc) ligands. Compound 2 is constructed from 1D chains that are linked by L ligands extending a 2D (4,4) grid. Compound 3 is a 3D framework with (4{sup 3})(4{sup 6}.6{sup 18}.8{sup 4}) topology, which is composed of trinuclear clusters and five-coordinated metal centers joined through 1,4-benzenedicarboxylate (p-bdc) and L ligands. Moreover, the fluorescent properties of L ligand, compounds 1 and 3 are also determined. - Graphical abstract: Three unprecedented complexes have been constructed from a new semirigid ligand 1,1'-bis(pyridin-3-ylmethyl)-2,2'-biimidazole (L) combined with benzenedicarboxylate isomers and different metal ions under hydrothermal conditions, which exhibit novel topologies. Luminescent properties of L ligand, compounds 1 and 3 are also determined.
