The interactions between platinum complexes and human serum albumin (HSA) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. Octahedral platinum (IV) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. In this study, the interaction between two Pt(IV) complexes ...

We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted

the charge transfer (ct) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in ccl4 solutions is investigated by chemical shift measurements relative to an external reference. the equilibrium parameters, q and dad of their weak molecular complexes, as found numerically modified cresswel- allred (c-a) method, is compared with graphically scat...

The macrocyclic complexes of biological importance with power transition metals are synthesized by template methodology leading to the formation of the complex [MLX] X2; where L is macrocyclic ligand derived from 3,4-diaminotoluene, 2,4-thiazolidinedione, M=Cr (III) and Fe(III) X is Cl-, CH3COO- or NO3_.Characterisation of these complexes are through with the assistance of elemental analyses(CH...

In this study, the substituent effect on the electronic, spectroscopic properties and thermodynamic parameters of neutral and oxidized states of ferrocylidene acetophenone complexes was investigated by adopting the hybrid meta exchange-correlation functional of M06-2X. The frontier orbitals and the highest occupied molecular orbitals–lowest unoccupied molecular orbitals gaps of the substituted ...
