摘要
合成了六水四(胍)双(伊甘酸)共晶(I)，并用单晶x射线衍射技术测定了(I)的分子结构和晶体结构。晶体体系为三斜晶系，空间群为P1和Z = 4。单元胞尺寸为a = 14.4774(8) a, b = 14.7735(8) a, c = 15.9316(1) a， α = 64.739(1)°，β = 70.185(1)°，γ = 70.185(1)°，V = 2871.22(17)A3。9198次反射的最终R值为0.0462 (I > 2σ(I))。晶体填充物主要由氢键相互作用来稳定。
Crystal Structure of a Proton-Transfer Self-associated Compound Tetrakis(guanidinium)bis(eosinate) hexahydrate
A co-crystal of tetrakis(guanidinium) bis(eosinate) hexahydrate (I) was synthesized, and the molecular and crystal structures of (I) were determined by a single-crystal X-ray diffraction technique. The crystal system is triclinic with a space group of P1 and Z = 4. The unit-cell dimensions are a = 14.4774(8)A, b = 14.7735(8)A, c = 15.9316(1)A, with α = 64.739(1)°, β = 70.185(1)°, γ = 70.185(1)°, V = 2871.22(17)A3. The final R value is 0.0462 for 9198 observed reflections (I > 2σ(I)). The crystal packing is predominantly stabilized by hydrogen-bond interactions.
