The crystal structure of the title compound, C(16)H(11)F(3)N(4)O(2)S, is stabilized in the form of polymeric chains by N-H⋯O inter-actions. In the mol-ecular structure, two S(5) ring motifs are formed by intra-molecular N-H⋯N and N-H⋯O hydrogen bonding and two S(6) rings are present due to N-H⋯O and C-H⋯S inter-actions. π-π inter-actions are present with distances of 3.2735 (17), 3.563 (2) and ...

The asymmetric unit of the title compound, C(21)H(17)Cl(2)N(3)O, contains two crystallographically independent mol-ecules with similar conformations. The benzotriazole ring is oriented at dihedral angles of 30.61 (5) and 43.36 (5)°, respectively, to the phenyl and dichloro-phenyl rings in one mol-ecule, and 32.25 (5) and 41.04 (5)° in the other. The dihedral angles between the phenyl and dichlo...

Mineralization studies were performed to examine the impact of N deprivation on microbial utilization of the N-heterocyclic herbicides, atrazine and cloransulam-methyl (C-M). Soil depleted by 130 years of cropping to Zea mays without fertilization was contrasted to soil from the same site regularly receiving fertilizers. Long-term N deprivation promoted rapid degradation of atrazine and the C-M...

The title compound, C(18)H(14)FN(3)O(2)S(2), was synthesized by the reaction of 5-(4-fluoro-phen-yl)-N-(4-methoxy-benzyl-idene)-1,3,4-thia-diazol-2-amine and mercaptoacetic acid. The thia-zolidinone ring adopts a twist conformation. The 4-methoxy-phenyl ring is almost perpendicular to the thia-diazole ring, making a dihedral angle of 88.4 (3)°. The 4-fluoro-phenyl ring is nearly coplanar with t...

The title compound, C(24)H(19)N(5)OS·H(2)O, was synthesized by the reaction of 4-benzoyl-3-methyl-1-phenyl-pyrazol-5-one and 2-hydrazino-1,3-benzothia-zole. Proton transfer leads to the formation of a zwitterionic structure and the mol-ecule exists in the enolate form. The pyrazolone ring makes dihedral angles of 35.4 (3), 69.7 (3) and 40.1 (3)° with the 1-phenyl, indirectly bound phenyl and be...
