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