Complex compounds of platinum (II) and (IV) with amino acids, peptides and their derivatives

Mixed Ligand Complexes of Gold (III) with Some Amino Acids and Dithiocarbamates or Dithiophosphates

“…4, 8, 12 and 16) where the sulfur atom replaces the carboxylate oxygen. Similar results were reported for the isostructural platinum(II) complexes with sulfur containing aminoacids [26]. Apparently the square planar preference for gold(III) might be the motive in which case the choice of using N and S binding sites are preferred regardless of the negative charge an oxygen.…”

Analysis for the stability of platinum‐containing species in soil samples using capillary electrophoresis interfaced on‐line with inductively coupled plasma mass spectrometry

“…It is striking that the quantity of PtC1,Z-in the extract remains constant during aging, probably due to the high chloride content of the sample. Chloride is known to stabilize chloroplatinates ( [9] and our observations). In the investigated concentration range (90 pg/L) degradation is slow (days and not hours), even without C1-stabilization (unpublished results).…”

“…Here it is applied for checking sample-and species stabilities in Pt standard solutions of low concentration, water eluates from Pt-treated soils and highway tunnel dust. It is known [9] that Pt species often show fast species transformations within hours. The extent of possible alterations just before analysis must be quantitated to differentiate them from transformations due to interactions with the soil.…”

Synthesis and characterisation of organo-platinum(II) complexes of the N,O-donor ligands hippuric acid (N-benzoylglycine) and N-phenylanthranilic acid

“…The coordination chemistry of amino acid ligands towards the platinum group metals has been extensively studied, [1,2,3] on account of the importance of such ligands in biological systems, and the utility of a number of platinum-based drugs for the treatment of cancer. However, there have been fewer studies on analogous complexes of ligands where the amine group of the amino acid is 'protected' by means of an acyl or sulfonyl [4] substituent.…”
