33′-Diphenyl-11′-22′-oxybis(21-phenyl­ene)diurea NN-dimethyl­formamide disolvate

摘要

In the structure of the title compound, C26H22N4O3·2C3H7NO, one of the DMF solvent mol­ecules is disordered over two sets of positions in a 0.5:0.5 ratio. In the 1,1′-[2,2′-oxybis(2,1-phenyl­ene)]bis­(3-phenyl­urea) mol­ecule, the two diphenyl­urea segments are linked via an ether O atom and are inclined at an angle of 53.80 (4)° to one another. In the crystal structure, classical N—H⋯O hydrogen bonds link each mol­ecule to two DMF solvent mol­ecules and these aggregates form columns down a through C—H⋯π inter­actions. Additional C—H⋯O inter­actions link the main mol­ecule and the solvent mol­ecules, forming columns of independent zigzag chains along b.
