Abstract

Graphical abstract: In this study, two new coordination polymers were synthesized at 120 and 170 °C using the same components. Complexes1 and2 are 1D and 2D coordination polymers. The most striking features of the complexes are that when the temperature is increased, the dimensionality is increased. Complexes1 and2 show blue emissions. Abstract: 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 complex1, 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 (complex2 ) was obtained with the sql topology. The o-pda ligand displayed different coordination modes in1 and2 . Moreover, thermal, photoluminescence and topological properties of the synthesized complexes were studied in detail.
