The title zinc bis(thiosemicarbazone) complex, [Zn(C 22 H 17 N 4 O 2 S) ], comprises two , S -donor anions, leading to a distorted tetrahedral donor set. resultant five-membered chelate rings are nearly planar and form dihedral angle of 73.28 (3)°. configurations about the endocyclic- exocyclic-imine bonds Z E respectively, that ethylene bond is . major differences in conformations ligands seen...

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...

The novel racemic secondary alcohol (±)-2-{[4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl]sulfanyl}-1-phenyl-1-ethanol (12) has been successfully synthesized through S-alkylation of 4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazole-3-thiol (10) in alkaline medium with 2-bromo-1-phenylethanone followed by reduction the corresponding ketone 11. All compounds were characterized IR, 1D (1H, 13C, DEPT...

By connecting tercarbazole (3Cz) and triphenyltriazine (TRz) units with a diphenyl ether group, we designed synthesized new donor-spacer-acceptor structure molecule 9′-(4-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenoxy) phenyl)-9′H-9,3′:6′,9″-tercarbazole (3Cz-o-TRz) as the multifunctional component of exciplex emitters. As expected, intermolecular charge-transfer transition is dominant for 3Cz-o-T...

keeping in view the promising potential of carbonic anhydrase inhibitor based antimicrobials and enhancement of carbonic anhydrase inhibitory activity by metal complexes of sulfonamides, with an aim to develop better antimicrobial agents we have attempted investigation of antimicrobial activity of metal complexes of 4-(2'-hydroxy phenyl imino) phenyl sulphonamide. sulfanilamide was taken a...

Geometric parameters of the title compound, C(24)H(20)N(2)O(2)S, are in the usual ranges. The central heterocycle makes dihedral angles of 41.29 (4) and 72.94 (5)° with the phenyl ring and the methoxy-phenyl ring, respectively.

The proton-ligand and metal-ligand stability constants of the complexes of Cu(II), Ni(II),Co(II) with 1-Benzothiazol2-yl-3-(2-hydroxy phenyl)-5-(4-methoxy phenyl) pyrazoline (L), 1-Benzothiazol-2-yl-3-(2-hydroxy phenyl)-5-phenyl pyrazoline (L), 1-Benzothiazol-2-yl-3-(2-hydroxy phenyl)-5-(4-chloro phenyl) pyrazoline(L), 1-Benzothiazol-2-yl3-(2-hydroxy-5-methyl phenyl)-5-(4-methoxy phenyl) pyrazo...

Some new 3-[(5-benzylidene-2-phenyl)-3, 5-dihydro-4-H-imidazol-4-one-3-(4-bezoylhydrazono)]-indole-2-ones (VIII) have been synthesized from different isatinhydrazones (II) by condensing with 2-phenyl-5-benzylidene- 3-N (4-acetyl phenyl)-1, 5-dihydro-imidazol-4-one (VII). Their chemical structures have been confirmed by IR, 1HNMR, MASS and by elemental analysis. Investigation of antimicrobial ac...
