Synthesis and characterization of monomeric siloxo palladium(II) complexes: crystal structure of [Pd(tmeda)(C6F5)(OSiPh3)]
2004
Abstract Mononuclear palladium-hydroxo complexes of the type [Pd(N–N)(C6F5)(OH)] [(N–N)=2,2′-bipyridine (bipy), 4,4′-dimethyl-2,2′-bipyridine (Me2bipy), or N,N,N′,N′-tetramethylethylenediamine (tmeda)] react with silanols HOSiR3 in toluene giving the corresponding siloxo complexes [Pd(N–N)(C6F5)(OSiR3)]. The X-ray crystal structure of [Pd(tmeda)(C6F5)(OSiPh3)] has been determined. In one of the two molecules in the asymmetric unit there is an intramolecular interaction by phenyl–pentafluorophenyl π-stacking.
Organoplatinum(II) Complexes Self-Assemble and Recognize AT-Rich Duplex DNA Sequences
2021
The specific recognition of AT-rich DNA sequences opens up the door to promising diagnostic and/or therapeutic strategies against gene-related diseases. Here, we demonstrate that amphiphilic PtII complexes of the type [Pt(dmba)(N∧N)]NO3 (dmba = N,N-dimethylbenzylamine-κN, κC; N∧N = dpq (3), dppz (4), and dppn (5)) recognize AT-rich oligonucleotides over other types of DNA, RNA, and model proteins. The crystal structure of 4 shows the presence of significant π-stacking interactions and a distorted coordination sphere of the d8 PtII atom. Complex 5, containing the largest π-conjugated ligand, forms supramolecular assemblies at high concentrations under aqueous environment. However, its aggreg…
