Preparation and topological properties of two structures with p-sulfobenzoic ligands and Zn2+ and Mn2+ ions

摘要

There has been recent interest in coordinated polymers due to their structural and topological properties; therefore, the search for efficient synthesis processes to construct these materials by exploiting different organic ligands has intensified. In this context, two coordinated polymers (Zn-psb and Mn-psb) consisting of p-sulfobenzoic acid and either Zn2+ or Mn2+ ions, respectively, were synthesized by crystallization in gel using ethambutol hydrochloride as a new crystallization agent. Both compounds crystallized in the triclinic system and space group P (1) over bar and have similar unit cell volumes with a difference of 2%. The crystal data for Zn-psb: a 8.080(4) angstrom, b 11.385(6) angstrom, c 12.282(6) angstrom, alpha = 97.402(4)degrees, beta = 106.530(4)degrees, and gamma = 110.445(5)degrees; and for Mn-psb: a = 8.055(5) angstrom, b = 10.152(7) angstrom, c = 12.541(8) angstrom, alpha = 99.084(6)degrees, beta = 95.358(5)degrees, and gamma = 106.090(6)degrees. Despite the structural similarity, two different networks (tfz-d and pcu for Zn-psb and Mn-psb, respectively) were formed, and their topological properties were explored by reticular chemistry.
