Synthesis and Crystal Structure of N,N'- Bis(p-nitrophenyl)-2,2'-(p-phenylene- dioxy)diacetamide DMF Monohydrate

摘要

A new complex of N,N'-bis(p-nitrophenyl)-2,2'-(p-phenylene-dioxy) diacetamide DMF monohydrate, C25H25N5O9H2O (Mr = 557.52), has been synthesized and its structure was determined by X-ray crystallography method.The crystal belongs to monoclinic system, space group P21/c with a = 7.2812, b = 25.5894, c = 14.3434 (A), β = 91.110(1)o, V = 2672.0(2) (A)3, Dc = 1.386 g/cm3, F(000) = 1168, μ = 0.109 mm-1 and Z = 4.The final R = 0.0493 and wR = 0.1173 for 3389 observed reflections with I > 2σ(I).The asymmetric unit of the title complex consists of monomeric N,N'-bis(p-nitrophenyl)-2,2'-(p-phenyleneioxy)diacetamide 1, one DMF and one water molecule, which are incorporated during recrystallization.The molecules are linked into a three-dimensional network by π…π interactions as well as intermolecular interactions among DMF, water molecule and 1.
