Molecular and Crystal Structure of Trans -2- p-N-methyl-N-(2'-hydroxyethyl)aminophenyl-nitroethene

摘要

The title compound trans-2-[p-N-Methyl-N-(2(-hydroxyethyl)amino] phenyl- nitroethene (C11H14N2O3, Mr = 222.24) crystallizes in the triclinic system, space group Pwith a = 5.138(1), b = 9.386(1), c = 12.282(1)?, ( = 108.929(8), ( = 94.70(1), ( = 99.28(1)(, V = 547.1(1)?3, Z = 2, Dc = 1.349g·cm-3, F(000) = 236, ( = 0.1mm-1, MoK( radiation (( = 0.71073?), R = 0.0698, wR = 0.2381 for 1948 observed reflections [I >2((I)] of 2875 independent reflections. The results show that the molecule with donor/(-conjugated/acceptor (D-(-A) structure has good planarity except C(1) and O(1), there is a high delocalization of ( electrons in the system. The molecules are linked by intermolecular hydrogen bonds.
