Methyl (2Z)-2-{(2Z)-3-[(cyclo-pentyl-idene)amino]-4-oxo-2-phenyl-imino-1,3-thia-zol-idin-5-yl-idene}acetate.

ABSTRACT: In the title compound, C17H17N3O3S, the thia-zole ring is nearly planar [maximum deviation = 0.015?(1)?Å for the ring N atom] and the cyclo-pentane ring has a twist conformation. The mol-ecular conformation is stabilized by a hypervalent inter-action between the S atom and the ester group carbonyl O atom, with an S?O distance of 2.7931?(10)?Å. In the crystal, C-H?O inter-actions generate chains of mol-ecules propagating along [110] and ?-? stacking inter-actions [centroid-centroid distance = 3.4677?(7)?Å] between the thia-zole rings organize these chains into (001) layers.

S-1,3-Benzothia-zol-2-yl (2Z)-2-(2-amino-1,3-thia-zol-4-yl)-2-(methoxy-imino)-ethane-thio-ate.

Project description:The title compound, C(13)H(10)N(4)O(2)S(3), is an acyl-ating agent which belongs to the thia-zole class of organic compounds. The dihedral angle between the benzene and thiazole rings, which are fused to each other, is 1.2?(2)° so the overall benzothiazole system is almost planar. Inter-molecular N-H?N inter-actions and weak C-H?O inter-actions between symmetry-related mol-ecules stabilize the crystal structure, forming three different ring motifs [R(2) (2)(8), R(2) (2)(10) and R(2) (2)(16)] in three dimensions.

Project description:The asymmetric unit of the title compound, C21H19N3O3S, contains two independent mol-ecules. In one mol-ecule, the 1,3-thia-zolidine ring forms dihedral angles of 86.19?(8) and 8.37?(8)° with the phenyl and benzene rings, respectively. The corresponding dihedral angles in the other mol-ecule are 69.60?(7) and 14.08?(7)°. The dihedral angle between the phenyl and benzene rings is 84.70?(8)° in one mol-ecule and 69.62?(8)° in the other. In the crystal, mol-ecules pack in layers approximately parallel to (10-2). There are weak C-H?O hydrogen bonds within these layers. Further weak C-H?O hydrogen bonding occurs between the layers to form a three-dimensional network. A weak C-H?? inter-action is also observed.

Crystal structure and Hirshfeld surface analysis of (<i>Z</i>)-4-chloro-<i>N</i>'-(4-oxo-thia-zol-idin-2-yl-idene)benzene-sulfono-hydrazide monohydrate.

Project description:The asymmetric unit of the title thia-zole derivative containing a sulfonyl-hydrazinic moiety, C9H8ClN3O3S2·H2O, consists of two independent mol-ecules and two water mol-ecules. The central parts of the mol-ecules are twisted as both the mol-ecules are bent at both the S and N atoms. In the crystal, N-H⋯N, N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions connect the mol-ecules, forming layers parallel to the ab plane. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from O⋯H/H⋯O (32.9%) and H⋯H (22.6%) inter-actions.
