To further explore the coordination possibilities of the flexible tripodal ligand, 4,4,4-(benzene-1,3,5-triyl-tris(oxy))tribenzoic acid (H3BTTB), two solvent-controlled three-dimensional (3D) manganese(II) coordination polymers, [Mn-3(BTTB)(2)(H2O)(4)](H2O)(2) (1) and [Mn-3(BTTB)(2)(DMF)(2)](DMF)(2) (2), were synthesized and characterized. Single crystal X-ray diffraction analysis indicates that in the Mn-II complexes the BTTB ligands exhibit two coordination modes, which have not been reported previously. Complexes 1 and 2 involve different one-dimensional (1D) rod-shaped metal-carboxylate secondary building units (SBUs). The 1D SBUs are further extended to afford two different three-dimensional (3D) frameworks with similar flu topology via linkage of the BTTB ligands. The results demonstrate that the reaction solvent as well as conformation and coordination mode of BTTB ligands play key roles on the formation of the final framework structures. Additionally, their luminescent properties were investigated.
