Schiff base, azetidinone and 4-thiazolidinone derivatives of para aminosalicylic acid were synthesised. It was planned to employ the structure based computer aided drug designing (CADD) to Schiff base, azetidinone and 4thiazolidinoneof para aminosalicylic acid. Approach was employed to understand the probable binding of para aminosalicylic acid on the active site of AMpC enzyme of HKY28 which w...

In the title complex, [ZnI(2)(C(14)H(21)BrN(2)O)]·CH(3)OH, the asymmetric unit consists of a mononuclear zinc(II) complex mol-ecule and a methanol solvent mol-ecule. The compound was derived from the zwitterionic form of the Schiff base 4-bromo-2-[3-(diethyl-amino)propyl-imino-meth-yl]phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand and ...

The title compound, [Cd(H(2)O)(6)][Cu(C(15)H(17)N(2)O(4))](2)·2H(2)O, has a chiral structure. Copper has a square-planar coordination with two N and two O atoms of the quadridentate chiral Schiff base ligand. The Cd(2+) ion is coordinated by six aqua ligands with a slightly distorted octa-hedral configuration. Ions are linked by O-H⋯O hydrogen bonds, and the [Cd(H(2)O)(6)](2+) cations and [CuL]...

One of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. In this paper, the authors have studied thermal behaviour for Schiff base ligand and their synthesized Cobalt, Nickel complexes. In this method, the sample is opposed to a controlled temperature change and its physical properties. Here we studied melting point and Tg...

A novel interesting hexadentate dibasic N(2)S(2)O(2) donor Schiff base ligand, H(4)dcsalpte, was synthesized by the condensation of 3-formylsalicylic acid and 1,2-di(o-aminophenylthio)ethane and characterized. The reactions of the ligand with different metal(II/III)salts under varied reaction conditions afforded a series of metal complexes. The ligand, H(4)dcsalpte, behaves either as a dibasic ...

The title compound, C(28)H(24)N(2)O(5), a flexible Schiff base ligand, was prepared in high yield by a Schiff base condensation of 3-methoxy-salicylaldehyde and bis-(4-amino-phen-yl) ether in methanol. The mol-ecule lies on a twofold rotation axis, and each half exhibits an imine E configuration and an O-H⋯N hydrogen bond. The dihedral angle between the two benzene rings attached to the central...

The title complex, [ZnI(2)(C(12)H(18)N(2)O)], is a mononuclear zinc(II) compound derived from the zwitterionic form of the Schiff base (E)-2-[(3-dimethyl-amino-propyl-imino)meth-yl]phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand, and by two iodide ions in a tetra-hedral coordination geometry. In the crystal structure, mol-ecules are lin...
