anions and molecular iodine [dI−I = 2.8499(5) A]. In 1, dimer Cu2I64− anion is composed by two edge-sharing CuI4 tetrahedra. Cu2I64− anions interact with I2 via strong I⋯I interaction to give [(Cu2I6)·2I2]4− clusters. Furthermore, electrostatic interactions between organic cations and inorganic clusters could be observed and contribute to the crystal packing. Finally, quantum chemistry calculation with
摘要 ibq·I、CuI与I2反应得到离子化合物(ipq)4[(Cu2I6)·2I2](1)(ipq+ = N-(异戊基)-喹啉鎓)的深红色块状晶体。在极性溶剂 DMF 中。化合物 1 在三斜晶系 [空间群 P 1 ¯ Z = 2, a = 10.4236(8) A, b = 12.1950(9) A, c = 15.6214(10) A, α = 95.879(2)°, β = 102.174(2)° 和 γ = 113.757(2)°]。如结构分析所示,1 由 ipq+ 阳离子、[Cu2I6]4- 阴离子和分子碘 [dI-I = 2.8499(5) A] 构成。在 1 中,二聚体 Cu2I64− 阴离子由两个共享边缘的 CuI4 四面体组成。Cu2I64− 阴离子通过强 I⋯I 相互作用与 I2 相互作用,产生 [(Cu2I6)·2I2]4− 簇。此外,可以观察到有机阳离子和无机簇之间的静电相互作用并有助于晶体堆积。最后,
