inorganic Rb 4 (SO 4 )(HSO 4 ) 2 (H 3 AsO 4 ) compound was prepared. It was found to crystallize in the monoclinic system (P2 1 space group) with the following lattice parameters: a = 5868 (1) A, b = 13,579(2) A, c = 11,809 (3) A and β = 94,737 (1)°. The structure is characterized by SO 4 2− , HSO 4 − and H 3 AsO 4 tetrahedra connected by hydrogen bridge to form two types of dimmer (H(8)S(2)O 4 − … S(1)O
摘要 制备了一种新型无机Rb 4 (SO 4 )(HSO 4 ) 2 (H 3 AsO 4 )化合物。发现它在具有以下晶格参数的单斜晶系(P2 1 空间群)中结晶:a = 5868 (1) A, b = 13,579(2) A, c = 11,809 (3) A 和 β = 94,737 (1 )°。该结构的特点是SO 4 2- 、HSO 4 - 和H 3 AsO 4 四面体通过氢桥连接形成两种类型的二聚体(H(8)S(2)O 4 - ... S(1)O 4 2-和 H(12)S(2)O 4 - ... H 3 AsO 4 )。这些调光器通过氢键 O(14) H(14)··O(4) 和 O(15) H(15)··O(2) 相互连接。它们还通过由 H 3 AsO 4 基团的氢原子 H(2)、H(3) 和 H(4) 确保的氢桥连接,以构建链 S(1)O 4 ⋯H 3 AsO 4平行于“a”,方向。铷阳离子由八个氧原子配位,Rb
