C 20 H 28 Cl 2 Zn4O 18 S 2 , monoclinic, P21/c (no. 14), a = 8.0835(16) Å, b = 17.389(4) Å, c = 11.576(2) Å, β = 106.59(3)°, CCDC no.: 1446931The crystal structure is shown in the gure. Tables 1-3 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialAll reagents and solvents were obtained from commercial sources and used without further puri cation. Di-4-pyridylsul de was synthesized following the procedure reported [1], which (470 mg, 2.5 mmol) was disolved in glacial acetic acid (15 mL) and 30% w/w hydrogen peroxide (1.5 mL) at room temperature. After two weeks the resuted solution was treated with water (20 mL), leading to crystalline
