Research on the Structure of One-dimensional Chain Calcium(II) Complex Material

A new Ca(II) complex material has been prepared by the reaction of calcium perchlorate with 4-amino-3-methyl-benzenesulfonic acid and sodium hydroxide, and was characterized by single-crystal X-ray diffraction. The results showed that the complex crystallizes in monoclinic, space group P2(1)/n with a = 0.63090(10) nm, b = 0. 70513(11) nm, c = 2.4262(4) nm, V = 1.0766(3) nm(3), Z = 2, F (000) = 562, R-int = 0.0252. Single-crystal X-ray diffraction analysis revealed that each calcium ion lies in six-coordinated environments, and the complex formed one dimensional chain structure through intramolecule and intermolecule hydrogen bonds and pi-pi stacking interaction.
