摘要
C25H28N2O6·0.50(C6H6)为单斜晶，C2/c。293 K时的单位胞尺寸为a = 13.968(2)， b = 25.185(3)， c = 15.050(2) a， β = 102.272(2)°，V = 5173.4(12)A3, Dx = 1.262 g/cm3, Z = 8。1463次反射的R值为R = 0.0766。分子间存在一个N1…N1距离为2.851(7)A的氢键。吡唑环采用扭曲包络构象。晶体中的分子以正常的范德华距离排列。
Heterocyclic Derivatives of Curcumin: Crystal Structure of 3,5-Bis[β-(4-acetoxy-3-methoxyphenyl)ethyl]pyrazole Benzene Solvate
C25H28N2O6·0.50(C6H6) is monoclinic, C2/c. The unit-cell dimensions at 293 K are a = 13.968(2), b = 25.185(3), c = 15.050(2)A, β = 102.272(2)°, V = 5173.4(12)A3, Dx = 1.262 g/cm3, and Z = 8. The R value is R = 0.0766 for 1463 reflections. There is an intermolecular hydrogen bond with an N1…N1 distance of 2.851(7)A. The pyrazole ring adopts a distorted envelope conformation. The molecules in the crystal are packed at the normal van der Waals distances.
