Synthesis and Crystal Structure of 2-（4-Nitrophenyl）- 1,2-benzisoselenazol-3（2H）-one DMF （1：1） Solvate

摘要

The title compound （C13HsN203Se＇C3H7NO） has been synthesized by a simple synthetic route and by recrystallization from DMF. The molecular structure of this compound was obtained by single-crystal X-ray diffraction. The compound crystallized in the triclinic space group Pi with a = 7.450（6）, b = 8.150（7）, c = 13.859（12） A, α = 75.014（14）, β = 83.072（18）, γ = 84.409（14）°, V= 805.0（12） A3, Z = 2 and R = 0.0271 for 2575 observed reflections with I 〉 2σ（I）. X-ray analysis reveals that not only intermolecular Se...O and C-H...O interactions, but also π...π stacking interactions exist in the adjacent molecules. The above three kinds of intermolecular interactions extend the complex into an infinite three-dimensional layered network.
