A series of chiral coordination polymers, namely, {[Zn-3(L)(3)(H2O)(3)]center dot H2O}(n) (1), [Cu-2(L)(2)](n) (2), [Cd-3(L)(3)(H2O)(2)](n) (3), [Zn-2(L)(2)(4,4'-biPY)(2)](n) (4), [Cu-2(L)(2)(4,4'-bipy)(2)](n) (5), {[Zn(L)(biim-4)]center dot H2O}(n) (6), [Cu(L)(biim-4)](n) (7) and [Zn-3(L)(3)(btb)(H2O)(2)](n) (8-10) (H2L=(S)-(-)-1,1'-binaphtho-2,2'-diacetic acid, 4,4'-bipy=4,4'-bipyridine, biim-4=1,1'-(1,4-butanediyl)bis(imidazole) and btb = 1,6-bis(1,2,4-triazol-1-yl)hexane) have been synthesized under hydro/solvothermal conditions. In complexes 1-3, L anions bridge Zn(II), Cu(II) and Cd(II) cations to form one dimensional (1D) chains, respectively. The structures of complexes 4 and 5 are isomorphous, in which metal ions are bridged by 4,4'-bipy ligands to furnish 1D columns with L branches. Complex 6 displays a 3D diamond topology. Complex 7 features an undulated sheet with two types of helical chains. Complexes 8-10 possess similar layer structures, but show different stacking modes. Complexes 4, 6 and 8 were characterized by non-linear optical properties. The UV-vis diffuse reflectance spectra for complexes 1-9 have been researched. The solid state photoluminescent properties for complexes 1, 3, 4, 6, 8 and 9 at ambient and low temperatures were also studied.
