2-(5-Bromopentyl)-4-chloro-5-[2-(4-methoxyphenyl)ethylamino]pyridazin-3(2H)-one
The asymmetric unit of the title compound, C(18)H(23)BrClN(3)O(2), consists of two mol-ecules which exhibit different conformations of the pentyl chains [C-C-C-C torsion angles of -60.4 (4) and 175.8 (3)°]. The crysal packing exhibits a chain structure, generated through the O atom of the pyridazinone forming a hydrogen bond with the N-H group of an adjacent mol-ecule.

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کاملN′-(5-Chloro-2-hydroxybenzylidene)-4-hydroxybenzohydrazide
The title Schiff base compound, C(14)H(11)ClN(2)O(3), was prepared by the reaction of 5-chloro-salicylaldehyde and 4-hydroxy-benzohydrazide. The mol-ecule exists in a trans configuration with respect to the methyl-idene group. The dihedral angle between the two benzene rings is 40.1 (2)°. An intra-molecular O-H⋯N hydrogen bond helps to stabilize the mol-ecular conformation. In the crystal struc...
متن کاملMethyl 5-chloro-2-(4-methylbenzenesulfonamido)benzoate
In the title compound, C(15)H(14)ClNO(4)S, the benzene rings are oriented at a dihedral angle of 85.42 (1)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a five-membered ring and an intramolecular C-H⋯O inter-action also occurs.
متن کاملN′-(5-Chloro-2-hydroxybenzylidene)-4-methoxybenzohydrazide
The asymmetric unit of the title compound, C(15)H(13)ClN(2)O(3), contains two independent hydrazone mol-ecules. Each mol-ecule adopts an E configuration with respect to the methyl-idene unit and forms an intra-molecular O-H⋯N hydrogen bond. The principal difference between the two unique mol-ecules is the relative orientation of the two benzene rings, the dihedral angles between them being 4.0 ...
