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, C_(25)H_(25)N_5O_9 H_2O (M_r = 557.52), has been synthesized and its structure was determined by X-ray crystallography method. The crystal belongs to monoclinic system, space group P2_1/c with a = 7.2812, b = 25.5894, c = 14.3434 A, β = 91.110(1)°, V= 2672.0(2) A~3, D_c = 1.386 g/cm~3, 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.
