文摘

Two new coordination polymers with the same components, namely [Zn(μ-opda)(μ-dib)_0.5(dib)]_n (1) and [Zn(μ₃-opda)(μ-dib)_0.5]_n (2), were synthesized under different temperatures and characterized by elemental analyses, IR spectroscopy, powder and single X-ray diffractions. The X-ray results showed that complex 1, synthesized at 120 °C, was a 1D ladder-like coordination polymer. When the reaction temperature was increased from 120 to 170 °C, a 2D coordination polymer (complex 2) was obtained with the sql topology. The o-pda ligand displayed different coordination modes in 1 and 2. Moreover, thermal, photoluminescence and topological properties of the synthesized complexes were studied in detail.
