Thermal behavior including the cold crystallization of a Schiff base complex bearing two methyl groups was investigated. Additionally, effect alkoxy chain length studied.

Two new heterocyclic Schiff bases of 4-amino-5-mercapto-3-H/propyl-1,2,4-triazole and 5-nitrofurfuraldehyde [HL(1-2)] and their cobalt, nickel, copper, and zinc complexes have been synthesized and characterized by elemental analyses, spectral (UV-Vis, IR, (1)H NMR, Fluorescence, and ESR) studies, thermal techniques, and magnetic moment measurements. The heterocyclic Schiff bases act as bidentat...

Metal complexes of Cu (II), Co (II), Ni (II) and Zn (II) of Schiff based derived from 5-chloro-2hydroxybenzaldehyde and 4-nitobenzenesulfonamide have been prepared and characterized on the basis of physical characteristics, micro-analytical data, H NMR, FTIR and UV spectrum data. The spectrum data confirm 1 coordination of Schiff base with metal through imine nitrogen and oxygen atom. These met...

Reactions of MnX(2) meltsalt (X = Cl and ClO(4)) and a quinquedentate Schiff base ligand together with its coligand azides in MeOH produced the unprecedented assembly of novel octa- and hexadecanuclear manganese clusters containing two and four alternant tetrahedral Mn(III)(3)Mn(II) cores bridged by Schiff base ligands and versatile azides groups. The magnetic measurements on both compounds ind...

Schiff-base ligands are potential anti-cancer, anti-bacterial and anti-viral agents and this activity tends to increase in metal(II) Schiff-base complexes. Some oxindole-Schiff base copper(II) complexes have shown potential antitumor activity towards deferent cells, inducing apoptosis in a process modulated by the ligand. Here, six novel copper(II) complexes with schiff base ligands were isolat...
