چکیده
In the title compound, C(11)H(19)N(3)O(5), the six-membered ring displays a half-chair conformation and the imidazolidine ring is essentially planar (r.m.s. deviation = 0.088 Å). An inter-molecular hydrogen bond between the hy-droxy O atom and a nitro O atom stabilizes the crystal packing.

In the title compound, C(13)H(22)N(4)O(2)S(2), the six-membered ring displays a half-chair conformation. The olefin amine unit is close to being coplanar with the imidazolidine ring (r.m.s. deviation = 0.059 Å). The dithiol-ane ring adopts a twisted conformation. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions.

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, wh...
