Reactions of a flexible fluorinated ligand, 2,3,5,6-tetrafluoro-1,4-bis(imidazol-1-ylmethyl) benzene (Fbix), with ZnX2 (X =OAc- or NO3-) lead to the formation of the two new ZnII coordination polymers [Zn(Fbix)(OAc)2]n (1) and {[Zn2(Fbix)3(NO3)2](NO3)2(H2O)3}n (2), which have been characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Although the ZnII centers of both 1 and 2 are in a similar tetrahedral coordination geometry, each ZnII ion in 1 is surrounded by two Fbix spacers and two terminal OAc- anions to form a highly undulated chain, whereas each ZnII ion in 2 is embraced by three Fbix ligands and one NO3- anion to result in a two-dimensional cationic network. Since 1 and 2 are synthesized under the same conditions, the structural differences between them are attributable to the difference of the counterions. The solid-state properties such as thermal stability and luminescence of 1 and 2 have also been studied briefly.

In this study, six coordination polymers (CPs), {[Ag2(L)(CF3SO3)]·CF3SO3·2H2O·DMF}n (1), {[Ag(L)]·SbF6·4DMF·H2O}n (2), {[Zn(L)0.5(I)2]·3.75H2O}n (3), {[Cd2(L)(I)4(H2O)(DMF)]·4H2O·3DMF}n (4), {[Hg2(L)(I)4]·H2O·4DMF}n (5) and {[Hg2(L)(Cl)4]·2H2O·3DMF}n (6), were obtained based on the designed X-shaped urea-based ligand. X-ray single crystal diffraction analysis revealed that complex 1 displayed a 3D (3,4)-connected {6·82}{64·82}-tcj net. Complex 2 featured a 2D 4-connected {43·63} sheet. Complexes 3 and 5 exhibited a 1D polymeric loop chain. Complex 4 displayed a 1D polymeric fishbone chain. Complex 6 showed a 2D 4-connected {44·62}-sql sheet. Structural comparison revealed that not only the metal ions, but also the anions played crucial roles in the control of final structures.
