Synthesis, Structure, and Spectroscopic Properties of Calcium Thiophenecarboxylate Polymers. Structural Comparison with Analogous Lead Complexes
Abstrakt
Three novel calcium coordination polymers [Ca(2tpCOO)2(2mpa)(H2O)]n (1), [Ca(3tpCOO)2(2mpa)(H2O)]n (2), and {[Ca(3tpacCOO)2(H2O)2]⋅⋅⋅H2O}n (3) (2tpCOO− or 3tpCOO− – thiophene-2- or thiophene-3-carboxylate, 3tpacCOO− – thiophene-3-acetate, 2mpa – 2-methylpropanal), were synthesised using a self-assembly method. The obtained polymers were characterised using SC-XRD, FTIR, UV-Vis DRS, thermogravimetric and luminescence analyses. The polymer fluorescence studies showed that calcium complexes can emit light of different colours ranging from violet (1) and blue (2) to green (3). The molecular structure of each polymer consists of a calcium ion at the centre of a dodecahedral coordination sphere. The crystal structure consists of one dimensional zigzag chains that form a three-dimensional network via π⋅⋅⋅π, C−H⋅⋅⋅π and O−H⋅⋅⋅O or O−H⋅⋅⋅S interactions. Additionally, a comparative structural analysis of CaCPs with lead(II) coordination polymers containing analogous linkers was performed as part of modelling studies to explore the substitution of calcium ions by lead ions in biological polymers.
