چکیده
In the title compound, C(8)H(15)N(3)O(4), the 2-(nitro-methyl-ene)imidazolidine fragment is close to being planar (r.m.s. deviation = 0.027 Å), which may be correlated with delocalization of the electrons and the effect of the strongly electron-withdrawing NO(2) group. An intra-molecular N-H⋯O link generates an S(6) ring. The same H atom also forms a weak inter-molecular N-H⋯O hydrogen bond, which results in C(7) chains propagating in [010].

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(9)H(15)N(3)O(4), the 1,3-dioxane ring displays a chair conformation and the five-membered ring is close to planar (r.m.s. deviation = 0.054 Å). An intra-molecular N-H⋯O hydrogen bond to one of the nitro-group O atoms generates an S(6) ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010] and a C-H⋯O link als...

The imidazolidine ring in the title compound, C(17)H(18)Cl(2)N(2)O(2), adopts a twist conformation. The observed conformation is stabilized by two intra-molecular O-H⋯N hydrogen bonds, with both N atoms acting as hydrogen-bond acceptors. The phenyl substituents are aligned at 70.0 (1) and 76.6 (1)° with respect to the best plane through the five atoms of the imidazolidine ring. Weak inter-molec...
