Abstract
An innovative thermostable 2-D layered Zn(II) compound, chemical terms are written as [Zn(3-pysa)2(H2O)2]n (1, 3-Hpysa = 3-pyridinesulfonic acid), has been generated from the solvothermal reactions of 3-Hpysa and Zn(NO3)2·6H2O. Its single crystal analysis was implemented via the single crystal X-ray diffraction analysis together with the powder X-ray diffraction, elemental analysis and thermogravimetric analysis. The crystal framework is of monoclinic P21/n space group and its crystal cell figures: a = 7.7499(5), b = 10.9923(6), c = 8.3430(5) Å, α = 90, β = 96.924(6), γ = 90°, V = 705.55(7) Å3, Z = 4. The 2D layers were finally combined to a 3-D supramolecular conformation through intermolecular H-bonds existing between coordinated H2O molecules and sulfonate oxygen atoms from adjacent layer. Its practical role in pulpitis treatment was estimated and the relevant mechanism was studied in the meantime.
