hydrothermal conditions. Polymers 1 and 2 are 2D structures with 63 and 44 topology. Polymer 3 shows a 4-connected 3D framework, and 4 features a 1D structure with single/double alternate linkers. The effects of the positions of carboxyl groups and the coordination characteristics of metal ions on the structures of the title coordination polymers were studied. The title coordination polymers show multi-functional
