title: 3,3'-Diphenyl-1,1'-[2,2'-oxybis(2,1-phenyl-ene)]diurea N,N-dimethyl-formamide disolvate.
abstract: In the structure of the title compound, C(26)H(22)N(4)O(3)·2C(3)H(7)NO, one of the DMF solvent mol-ecules is disordered over two sets of positions in a 0.5:0.5 ratio. In the 1,1'-[2,2'-oxybis(2,1-phenyl-ene)]bis-(3-phenyl-urea) mol-ecule, the two diphenyl-urea 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 mol-ecule to two DMF solvent mol-ecules and these aggregates form columns down a through C-H⋯π inter-actions. Additional C-H⋯O inter-actions link the main mol-ecule and the solvent mol-ecules, forming columns of independent zigzag chains along b.
