Diethyl {(4-methoxy-phen-yl)[5-(4-nitro-phen-yl)-1,3,4-thia-diazol-2-ylamino]meth-yl}phospho-nate.

ABSTRACT: The title compound, C(20)H(23)N(4)O(6)PS, was synthesized by the reaction of N-(4-methoxy-benzyl-idene)-5-(4-nitro-phen-yl)-1,3,4-thia-diazol-2-amine and diethyl phosphite. The thia-diazole and nitro-substituted phenyl rings in the mol-ecule are approximately coplanar, the dihedral angle being 5.3?(2)°. The dihedral angle formed by the mean plane through all non-H atoms of both the thia-diazole and the nitro-substituted phenyl ring with the plane of the meth-oxy-substituted phenyl ring is 48.9?(2)°. In the crystal structure, mol-ecules form centrosymmetric dimers as a result of N-H?O bonds involving amine H and phosphine oxide O atoms.

Dimethyl [(4-fluoro-phen-yl)(6-methoxy-benzothia-zol-2-ylamino)meth-yl]phospho-nate.

Project description:In the mol-ecule of title compound, C(17)H(18)FN(2)O(4)PS, both the benzene ring with its conjunction C atom and the benzothia-zole ring with its conjunction N atom are close to planar (the maximum deviations are 0.0267 and 0.0427?Å for the benzene and benzothiazole rings, respectively), the dihedral angle between the planes of the benzothia-zole and benzene rings is 119.05?(3)°. The mol-ecular packing is stabilized by inter-molecular N-H?O, C-H?N and C-H?F hydrogen bonding, and by C-H?? and ?-? stacking inter-actions [centroid-centroid distances = 2.99?(2), 2.96?(3), 2.88?(2) and 3.773?(4)?Å].

(2R)-2-Cinnamoylamino-N-[5-(4-methoxy-phen-yl)-1,3,4-thia-diazol-2-yl]propanamide.

Project description:The asymmetric unit of the title compound, C(21)H(20)N(4)O(3)S, contains two independent mol-ecules. The dihedral angles between the two benzene rings are 47.6?(1) and 30.2?(1)°, the corresponding values between the p-methoxy-benzene and thia-diazol rings are 12.3?(1) and 24.7?(1)°, respectively, for the two mol-ecules. The conformations of the N-H and C=O bonds are anti with respect to each other. The enone groups show a trans configuration. The crystal structure is stabilized by N-H?O and N-H?N inter-actions. The absolute structure could not be determined from the X-ray data but the absolute configuration has been assigned by reference to an unchanging chiral centre in the synthetic procedure.

Project description:In the mol-ecule of the title compound, C(18)H(13)Cl(2)N(3)O(2)S(2), the thia-zolidinone ring has an envelope conformation with the S atom displaced by 0.394?(3)?Å from the plane of the other ring atoms.

The 2,4-dichloro-phenyl ring is oriented at dihedral angles of 84.21?(4) and 83.55?(3)° with respect to the thia-diazole and 4-methoxy-phenyl rings, respectively. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers.

Thus, all of the rings are nearly coplanar. In the crystal structure, inter-molecular O-H?N and C-H?O hydrogen bonds link the mol-ecules.

Project description:In the title compound, C(14)H(17)N(2)O(4)P·CH(3)OH, the planes of the pyridinium-2-ylamino and 2-hydroxy-phenyl groups form a dihedral angle of 75.6?(1)°, with the pyridinium NH group and the 2-hydroxy-phenyl OH group pointing in opposite directions. Three intra-molecular hydrogen bonds are observed. Two phospho-nate and two methanol mol-ecules are connected by O-H?O hydrogen bonds as a centrosymmetric dimeric cluster, and inter-act further with other dimeric clusters via N-H?O, O-H?O and C-H?O hydrogen bonds and C-H?? inter-actions, resulting in a sheet structure.
