RISCrystal growth and intramolecular hydrogen bond effects on activity of a novel Schiff base ligand: An experimental and theoretical approach
Reaction of thiosemicarbazide with alkyl halides produce isothiosemicarbazides which in condensation reactions with aldehydes or ketones could yield isothiosemicarbazones. A new tridentate Schiff base compound, salicylaldehyde S...
Novel Complexes of isothiosemicarbazone with MoO2 moiety
We report 4-methoxysalicylaldhyde S-allyl isothiosemicarbazone (HL) and its Mo(VI) complexes, [ML]. The crystal structure analysis indicates that the metal has six-coordinate distorted octahedral geometry. All experimental results confirmed that HL...
Synthesis a new uranyl isothiosemicarbazone complex with supramolecular architecture and UO2L(OMe)propanol formula
Isothiosemicarbazone is one of the most important compounds as N2O2 donor ligands. The N2O2 donor ligands and their complexes are great importance in chemistry as they provide synthetic models for the metal-containing sites in metallo...
HSA-interaction studies of some novel uranyl complexes of isothiosemicarbazone
reports of biological properties of isothiosemicarbazones and their
metal complexes. Among them, anticancer features are the most salient [3]. On the other hand, some isotopes of uranium especially 230U are utilized in medicine because...
Synthesis, spectroscopic investigation and crystal structure of some novel uranyl complexes of isothiosemicarbazones
The metal complexes of thiosemicarbazones show versatile and interesting structures as well as extensive range of biological properties [1]. In isothiosemicarbazone compounds –as derivatives of thiosemicarbazones- an alkyl group binds...
