چکیده
A series of mono-cationic dinuclear have been synthesized using ((pyridi picolinamide (L2) ligands: [(h6-arene C5Me5)2M2(m-L1)Cl3]þ (M 1⁄4 Rh, 4 p-PrC6H4Me, 7; C6Me6, 8), [(h-C5Me isolated as their hexafluorophosphate IR spectroscopy. The solid state struc ray crystallographic studies. Interestin nitrogen atoms whereas the second terminal chloride ligands. Fascinatin both ruthenium centers having h6-ar atom between the two metal centers N,O and N,N fashion. * Corresponding author.

The binding assessment with human serum albumin of novel six-coordinate Pt(IV) complexes, containing bidentate nitrogen donor/methyl ligands
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 ...
