چکیده
In the title compound, C(9)H(9)ClN(2), a substituted imidazoline, the six- and five-membered rings are twisted from each other, making a dihedral angle of 17.07 (5)°. In the crystal structure, a short Cl⋯Cl [3.3540 (3) Å] inter-action is observed. Neighbouring mol-ecules are linked together by inter-molecular N-H⋯N hydrogen bonds into a one-dimensional infinite chain along the [101] direction and short Cl⋯Cl contacts link the chains into a three-dimensional network. There is also a significant π-stacking inter-action between the planar sections of the six- and five-membered rings.

In the title compound, C(16)H(13)ClN(4)S, the thienopyridine fused-ring system is nearly planar (r.m.s. deviation = 0.0333 Å) and forms a dihedral angle of 4.4 (3)° with the attached dihydro-imidazole ring (r.m.s. deviation = 0.0429 Å) allowing for the formation of an intra-molecular (exocyclic amine)N-H⋯N(imine) hydrogen bond. The benzene rings of the disordered (50:50) -N(H)-C(6)H(4)Cl residu...

Radicals form networks of OH... ON and OH...Me(nitroxide) interactions. In 2, a frustrated network forms with insufficient N-O units to form extended chain interactions. The magnetism of 1 fits a 1-D Heisenberg model with J/k=-25 J mol(-1), while 2 shows more complex exchange behaviour consistent with its disordered crystal lattice.

In the title compound, C(18)H(17)ClN(2)O(2), the benzene rings form dihedral angles of 6.69 (6) and 74.88 (5)° with the 4,5-dihydro-1H-pyrazole ring. The benzene rings form a dihedral angle of 76.67 (5)° with each other. In the crystal, mol-ecules are linked via bifurcated (C,C)-H⋯O hydrogen bonds into chains along [010]. The crystal structure is further consolidated by C-H⋯π inter-actions.
