Construction of Zn(II) Linear Trinuclear Secondary Building Units from A Coordination Polymer Based on α-Acetamidocinnamic Acid and 4-Phenylpyridine Ejarque, Daniel Calvet Pallàs, Maria Teresa Font Bardia, Ma. Mercedes Pons, Josefina Polímers Cristalls moleculars Polymers Molecular crystals The synthesis and characterization of one coordination polymer and two trinuclear complexes are presented. The coordination polymer [Zn2( -O,O'-ACA)2(ACA)2(4-Phpy)2]n (1) has been obtained by the reaction between Zn(OAc)2 2H2O, -acetamidocinnamic acid (HACA), and 4-phenylpyridine (4-Phpy) using EtOH as solvent. Its recrystallization in CH3CN or EtOH yields two trinuclear complexes, both having pinwheel arrays with formulas [Zn3( -ACA)6(4-Phpy)2] 4CH3CN (2 4CH3CN) and [Zn3( -ACA)6(EtOH)2] 4EtOH (3 4EtOH), respectively. These trinuclear species, unavoidably lose their solvent co-crystallized molecules at RT yielding the complexes [Zn3( -ACA)6(4-Phpy)2] (2) and [Zn3( -ACA)6(EtOH)2] (3). In addition, compound 2 has also been obtained reacting Zn(OAc)2 2H2O, HACA, and 4-Phpy in a 1:2:2 ratio using CH3CN as solvent. Compounds 1-3 have been characterized by analytical and spectroscopic techniques. Furthermore, single crystals suitable for X-ray di raction method for compounds 1, 2 4CH3CN, and 3 4EtOH were obtained and their supramolecular interactions have been studied and discussed, showing 2D supramolecular planes for the trinuclear complexes and a 3D supramolecular network for the coordination polymer. Finally, the supramolecular interactions of 2 4CH3CN and 3 4EtOH have been compared using Hirshfeld surface analysis and electrostatic potential calculations. 2021-02-23T14:06:34Z 2021-02-23T14:06:34Z 2020-08-09 2021-02-23T14:06:34Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1420-3049 https://hdl.handle.net/2445/174206 703401 32784822 eng Reproducció del document publicat a: https://doi.org/10.3390/molecules25163615 Molecules, 2020, vol. 25, num. 16 https://doi.org/10.3390/molecules25163615 cc-by (c) Ejarque, Daniel et al., 2020 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess 23 p. application/pdf MDPI Articles publicats en revistes (Mineralogia, Petrologia i Geologia Aplicada)
