Molecular and crystal structure of trans-2-[p-N-methyl-N-(2 '-hydroxyethyl)amino]phenyl-nitroethene

The title compound trans-2-[p-N-Methyl-N-(2'-hydroxyethyl)amino] phenyl-nit roethene (C11H14N2O3, Mr = 222.24) crystallizes in the triclinic system, sp ace group P (1) over bar with a = 5.138(1), b = 9.386(1), c = 12.282(1)Angs trom, alpha = 108.929(8), beta = 94.70(1), gamma = 99.28(1)degrees, V = 547 .1(1)Angstrom (3), Z = 2, D-c = 1.349g . cm(-3), F(000) = 236, mu = 0.1mm(- 1), MoKalpha radiation (lambda = 0.71073 Angstrom), R = 0.0698, wR = 0.2381 for 1948 observed reflections [I >2 sigma (I)] of 2875 independent reflect ions. The results show that the molecule with donor/pi -conjugated/acceptor (D-pi -A) structure has good planarity except C(1) and O(1), there is a hi gh delocalization of pi electrons in the system. The molecules are linked b y intermolecular hydrogen bonds.
