从1，2，4，5-四氯苯开始，以两个步骤制备苯1，2，4，5-四磺酸（H4 B4 S）。H4 B4 S和Cu 2（OH）2（CO 3）的含水反应混合物的缓慢蒸发导致[Cu 2（B4 S）（H2O）8] · 0.5 H2O的浅绿色单晶。X-射线单晶结构分析表明该化合物为三斜晶系[P-1，Z = 1，a = 710.0（1），B = 713.7（1），c = 1077.1（2）pm，α = 98.41（2）°，β = 102.91（2）°，γ = 100.69（2）°]。在晶体结构中，Cu 2+离子被四个水分子和两个单齿磺酸根阴离子配位，产生四方扭曲的[CuO 6]八面体。阴离子与铜离子连接，形成沿[110]方向沿着延伸的梯形链。根据DTA/TG研究，化合物的脱水在240°C完成，无水磺酸盐的分解在340°C开始。
Benzene 1,2,4,5-tetrasulfonic acid (H4B4S) was prepared in two steps starting from 1,2,4,5-Te¬tra¬chlorobenzene. Slow evaporation of an aqueous reaction mixture of H4B4S and Cu2(OH)2(CO3) led to light green single crystals of [Cu2(B4S)(H2O)8] • 0.5 H2O. X-ray single crystal investi¬ga¬tions revealed the compound to be triclinic [P-1, Z = 1, a = 710.0(1), b = 713.7(1), c = 1077.1(2) pm, α = 98.41(2)°, β = 102.91(2)°, γ = 100.69(2)°]. In the crystal struc-ture the Cu2+ ions are coordinated by four water molecules and two monodentate sulfo¬na¬te anions yielding a tetragonally distorted [CuO6] octahedron. The anions are connected to fur-ther copper ions leading to ladder shaped chains running along the [110] direction. Accor¬ding to DTA/TG investi¬gations the dehydration of the compound is finished at 240°C and the de-com¬position of the anhydrous sulfonate starts at 340°C.
