Controllable Assembly of Two Zn(Ⅱ) Polymers via Varying Auxiliary Ligand: From 4-Connected cds Net to 4-Connected sql Tetragonal Plane Net

摘要

Two new Zn(Ⅱ) coordination polymers, namely [Zn(H_2ODPT)(bpe)(H_2O)]_n (1) and [Zn(H_2ODPT)(bpp)]_n (2) (H_4ODPT = 4,4'-oxydiphthalic acid, bpe = 1,2-bis(4-pyridyl)-ethane, bpp = 1,3-bis(4-pyridyl)-propane) were successfully synthesized via varying auxiliary ligands. Single crystal X-ray analysis reveals that 1 features a three-dimensional extended framework, which can be simplified into a 4-connected cds topological network; and, 2 features a two-dimensional layered framework, which can be simplified into a 4-connected sql tetragonal plane net. In addition, the luminescent and thermal stabilities properties were also investigated.
