Four new coordination compounds, namely {[Cd3(L) 2(μ3-OH)2(H2O)]·H 2O}n (1), {Ni(L)(bipy)}n (2), {Cu 3(L)2(bipy)(μ2-OH)2(DMF) 2}n (3), and {Co2L2(H 2L)(H2O)}n (4), have been synthesized by the solvothermal reaction of 4,4′-(hexafluoroisopropylidene)bis(benzoic acid) (H2L) with different transition metal ions in the presence of co-ligand 4,4′-bipyridine (bipy). Compound 1 displays a three-dimensional (3D) framework containing infinite bands constructed of heptanuclear cadmium clusters. In compound 2, [Ni2C2O4] secondary building units (SBUs) are linked by L2- ligands into a 1D ribbon, which are further assembled into a two-dimensional (2D) non-interpenetrated structure with {44·62} topology. Compound 3 possesses a 3D framework with a new topology of {43} 2{46·614·88} net, while the structure of 4 is a duplicate interpenetrated 3D framework with {412·63} net. Temperature-dependent magnetic studies reveal that 3 exhibits ferromagnetic coupling between adjacent Cu(ii) ions. The photoluminescent property of 1 has been studied in the solid state at room temperature.
