چکیده
In the title compound, C(6)H(11)N(3)O(3), the imidazolidine NH group is involved in a three-center N-H⋯O hydrogen bond, with intra-molecular and inter-molecular branches, to the nitro group O atoms. The centrosymmetric dimers that are formed are further connected by O-H⋯O hydrogen bonds between the hy-droxy and nitro groups into a two-dimensional polymeric structure extending parallel to (101).

In the title compound, C(27)H(27)Cl(2)N(7)O(4)S, the amide groups bearing the N-S group and the tert-butyl group have s-trans conformations. The steric size of the tert-butyl and [(6-chloro-3-pyrid-yl)meth-yl]imidazolidin-2-yl-idene groups cause the 2-chloro-benzoyl group and the benzyol group to be directed away from one another, forming a dihedral angle of 60.62 (17)°. The central N-N bond ad...
